The title compounds, a hydrogen-bonded linear chain, [Mn(C18H18N2O4)(H2O)2]ClO4, (I), a hydrogen-bonded pseudo-dimer, [Mn(C16H10Cl4N2O2)(CH4O)(H2O)]ClO4, (II), and a dimer, [Mn2(C18H18N2O4)2(CH4O)2](ClO4)2, (III), respectively, have been structurally characterized. The three complexes are completely different in their structural features, despite identical counter-anions and only slight modification of the substituents in the ligands. Complex (I) affords an elongated octahedral coordination environment, with axial Mn—O(water) distances of 2.259 (3) and 2.313 (3) Å, which forms hydrogen-bonded linear chains along the crystallographic c axis. Hydrogen-bonded pseudo-dimeric compound (II) also affords an elongated octahedral coordination environment, with axial Mn—O(CH3OH) = 2.222 (3) Å and Mn—O(water) = 2.266 (3) Å. Dimeric complex (III) is centrosymmetric and consists of distorted octahedral Mn atoms, with axial Mn—O(CH3OH) = 2.242 (2) Å and Mn—O(phenolate) = 2.348 (1) Å, connected via bridging O atoms from one of the ligands. The magnetic properties of the three complexes are described.

For (I), treatment of equimolar quantities of 5-methoxysalicylaldehyde (0.30 g, 2.00 mmol), ethylenediamine (0.30 g, 0.50 mmol) and manganese(III) acetate dihydrate (0.27 g, 1.00 mmol) in methanol (50 ml) at 323 K for 2 h gave a brown solution. After adding sodium perchlorate hydrate (0.70 g, 5.00 mmol) and stirring for 323 K for 1 h, the resulting solution was filtered and allowed to stand for two weeks at 298 K. Brown crystals of (I) suitable for X-ray crystallography were obtained from the filtrate. Analysis, found: C 41.50, H 4.29, N 5.17%; calculated for C18H22ClMnN2O10: C 41.84, H 4.29, N 5.42%; IR (KBr): 1627 cm−1 (C═N band); m.p. 604 K (decomposition); UV–vis (diffuse reflectance): 13300, 16700 and 18300 cm−1; magnetic moment 4.77 BM at 294 K. For (II), the same preparation procedure was employed as given for (I), using 3,5-dichlorosalicylaldehyde (0.38 g, 2.00 mmol) instead of 5-methoxysalicylaldehyde. Analysis, found: C 33.60, H 2.60, N 4.55%.; calculated for C34H36CuN2O4: C 68.04, H 6.05, N 4.67%; IR (KBr): 1636 cm−1 (C═N); m.p. 542 K (decomposition); UV–vis (diffuse reflectance): 13200 and 16700 cm−1; magnetic moment 4.54 BM at 294 K. For (III), the same preparation procedure was employed as given for (I), with 3-methoxysalicylaldehyde (0.30 g, 2.00 mmol) instead of 5-methoxysalicylaldehyde. Analysis found: C 44.50, H 4.29, N 5.17%; calculated for C19H22ClMnN2O9: C 44.50, H 4.32, N 5.46%; IR (KBr): 1621 cm−1 (C═N); m.p. 560 K (decomposition); UV–vis (diffuse reflectance): 18300 cm−1; magnetic moment 4.48 BM at 294 K.
For (I), all H atoms were located in a difference Fourier map and refined using a riding model, with O—H = 0.96 Å and Uiso(H) = 1.2Ueq(O), and C—H = 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C). There is positional disorder of atoms C8 and C16 over two equally occupied sites. It was assumed that the ethylenediamine moiety has two possible conformations, namely N1—C8A(H8A1/H8A2)—C16A(H16A/H16B)—N2 and N1—C8B(H8B1/H8B2)—C16B(H16C/H16D)—N2. For (II), H atoms were placed in geometrically calculated positions and refined using a riding model, with O—H = 0.84 Å and Uiso(H) = 1.2Ueq(O), and C—H = 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C). Atoms H17A–C and H17D–F, bound to the methyl group C17, were modelled as idealized disordered groups with equal occupancy factors. For (III), H atoms were located in a difference Fourier map and refined using a riding model, with C—H = 0.93–0.97 Å and Uiso(H) = 1.2Ueq(C), except for atom H5, which was fixed in its difference map position. Atoms H19A–C and H19D–F, bound to methyl group C19, were modelled as idealized disordered groups with equal occupancy factors.

Recently, photomagnetic functional complexes have been studied widely (Sato, 2003; Sato et al., 2003). One of the hypotheses for the discovery of such materials is to examine complexes which exhibit ready structural changes and valence or spin transitions. For example, a certain FeII complex exhibits spin-crossover due to Jahn–Teller distortion (Marchivie et al., 2003; Kambara, 1979). Schiff base MnIII complexes have attracted considerable attention due to their catalysis and magnetism. Chiral catalysts are often employed for Kochi–Jacobsen–Katsuki enantioselective epoxidation (Korendovych & Rybak-Akimova, 2004; Martinez et al., 2002; Reger & Janda, 2000; Khavrutskii et al., 2003a,b Which one?). Various photocatalytic reactions, including photocleavage of DNA (Sakamoto et al., 1998), photophysical properties (Cozzi et al., 2003) and photosystem II models (Ashmawy et al., 1985; Aurangzeb et al., 1994; Bermejo et al., 1996), have been studied for many years. On the other hand, numerous dimeric high-spin Schiff base MnIII complexes exhibit ferromagnetism (Miyasaka et al., 2002). These building blocks have potential in the design of new single-molecule magnets (Choi et al., 2004), hydrogen-bonded assemblies (Wernsdorfer et al., 2002) or multi-nuclear clusters (Mukhopadhyay et al., 2004). However, axially compressed complexes undergoing the Jahn–Teller effect are rare for analogous MnIII complexes (Shongwe et al., 2001). The 5D ground state may split into 5T2 g and 5Eg terms, and Jahn–Teller distortion removes the orbital degeneracy of the 5Eg ground state to give the orbital singlet lowest in energy, either 5A1 g or 5B1 g (Kennedy & Murray, 1985). The spin degeneracy of the 5A1 g or 5B1 g states is further removed by spin-orbit coupling, which gives rise to zero-field splitting, D. Axial elongation results in the 5B1 g level lying lowest with negative D, while axial compression leads to 5A1 g with positive D. Here, we present three new Schiff base MnIII complexes, the title compounds, (I)–(III). Despite only slight modification of the substituents and identical counteranions, they are different in their dimeric features involving the axial coordination bonds. The three complexes are a hydrogen-bonded chain of pseudo-dimers, (I), a pseudo-dimer, (II), and a dimer, (III).
In complex (I) (Fig. 1), the central MnIII ion adopts an elongated octahedral coordination geometry, with the displacement of the Mn1 ion from the O1/N1/N2/O2 least-squares plane being 0.012 (2) Å. Both axial sites are occupied by water ligands with a T value of 0.842, where T = RS/RL denotes the ratio of equatorial and axial mean bond lengths undergoing the Jahn–Teller effect (Hathaway & Billing, 1970). The ethylenediamine moiety adopts a λ conformation, with an N1—C8A—C16A—N2 torsion angle of 48.3 (10)° [or N1—C8B—C16B—N2 = 46.0 (12)°]. The angle between the least-squares planes of the aromatic rings of the ligands is 4.43 (13) °, which indicates near planarity of the overall molecular structure.
In the crystal of (I), adjacent molecules are linked by hydrogen bonds [O5···O3i = 2.929 (3) Å, O5···O1i = 2.928 (3) Å, O5···O4i = 2.984 (3) Å, and O5···O2i = 2.949 (3) Å; symmetry code: (i) 1 − x, 1 − y, 1 − z] to form hydrogen-bonded pseudo-dimers, with additional face-to-face π–π stacking interactions between the phenyl groups (C5···C9 = 3.54 Å and C4···C10 = 3.56 Å). Furthermore, intermolecular hydrogen bonds [O6···O8 = 3.029 (6) Å and O6···O8ii = 2.839 (6) Å; symmetry code: (ii) 1 − x, 1 − y, 2 − z] between these pseudo-dimers and perchlorate counter-ions result in hydrogen-bonded linear chains along the crystallographic c axis. Finally, there is an additional edge-to-face interaction to the phenyl group of a molecule adjacent to the linear chain (symmetry code: 1 − x, y − 1/2, 3/2 − z), with C4···C10 = 3.30 Å.
In pseudo-dimeric complex, (II) (Fig. 2), the central MnIII ion also adopts an elongated octahedral coordination geometry, in which the displacement of the Mn1 ion from the O1/N1/N2/O2 least-squares plane is 0.029 (2) Å. The two axial ligands are water and methanol, and the mean T value is 0.866. The ethylenediamine moiety again adopts a λ conformation, with an N1—C8—C16—N2 torsion angle of 44.4 (4)°. Although the angle between the least-squares planes of the aromatic rings on both sides of the ligand is 3.00 (18)°, the overall molecular shape is a stepped conformation.
In the crystal of (II), adjacent molecules form centrosymmetric hydrogen-bonded pseudo-dimers [O4···O1iii = 2.845 (3) Å, O4···O2iii = 2.970 (4) Å, O4···Cl2iii = 3.270 (1) Å and O4···Cl3iii = 3.246 (3) Å; symmetry code: (iii) 1 − x, 1 − y, −z], with the shortest π–π stacking interaction between the phenyl groups, C4···C13 = 3.42 Å. Moreover, hydrogen bonds [O3···O7 = 2.834 (6) Å] are formed between the axial methanol and the perchlorate ion.
As observed for (I) and (II), the MnIII ion of the dimeric complex, (III) (Fig. 3), shows an elongated octahedral coordination geometry, which comprises the tetradentate Schiff base ligand. A methanol ligand occupies the outer axial site, while the phenolate O atom of the adjacent monomer occupies the inner axial site. The geometric parameters of the bridging moiety are O1—Mn1iv = 2.348 (1) Å, O1—Mn1—O1iv = 80.26 (5)°, Mn1—O1—Mn1iv = 99.74 (5)° and Mn1···Mn1iv = 3.275 (1) Å [symmetry code: (iv) 1 − x, 1 − y, 1 − z]. The displacement of the Mn1 ion from the O1/N1/N2/O2 least-squares plane is 0.055 (1) Å. The T values are 0.865 and 0.826 (average 0.846) for the methanol and phenolate O atoms, respectively. It should be noted that the in-plane coordination bond distance [Mn1—O1 = 1.921 (1) Å] is considerably longer than usual, because the phenolate atom O1 also takes part in bridging, forming the dimers. The ethylenediamine moiety adopts a λ conformation, with an N1—C8—C16—N2 torsion angle of 44.9 (2)°. The angle between the least-squares planes of the aromatic rings of the ligands is 18.70 (7)°, which results from an overall stepped conformation.
In the crystal of (III), the perchlorate anions and dimers are packed alternately, with the shortest π–π stacking distance being between atom C1 and atom C14 in the adjacent phenyl group (symmetry code: 1 − x, 1 − y, 1 − z), of about 3.33 Å. An intramolecular hydrogen bond [O5···O8 = 2.767 (3) Å] is formed between the axial methanol and the perchlorate ion.
The three complexes are quite different in their structural features. It is likely that substitution of the aromatic ring at the 5-position by methoxy in (I) and Cl in (II) prevents the formation of dimers, as seen for (III), and instead hydrogen-bonded pseudo-dimeric systems are formed. Indeed, both the steric and electronic features of Schiff base ligands, namely the electron-donating methoxy group and the electron-withdrawing Cl group, considerably influence the Jahn–Teller distortion of the axial Mn—O bonds. It is expected that electron-donating substituent groups result in a large Jahn–Teller elongation and ferromagnetism, due to the orthogonal eg and dπ orbitals of the MnIII ion.
The structural differences reflect the overall magnetic properties for compounds (I)–(III). The variable-temperature magnetic susceptibility was measured in the range 2–300 K, and the plot of effective magnetic moment versus T is given in Fig. 4. On lowering the temperature to about 50 K, the magnetic moment was kept almost constant for (I)–(III). It then gradually increased to more than 6 BM at 8 K and then decreased for (I), while (II) and (III) showed a decrease at about 20 K and reached less than 2 BM at 2 K. By analogy with related complexes (Saha et al., 2004), the overall magnetic interaction of (I) is ferromagnetic, obeying χ = [Ng2β2/k(T-α)][A/B], where A = 30 + 14exp(−8 J/kT) + 5exp(−14 J/kT) + exp(−18 J/kT), B = 9 + 7exp(−8 J/kT) + 5exp(−14 J/kT) + 3exp(−18 K/kT) + exp(−10 J/kT), with the best-fit parameters of J,K = 1.25 K, g = 1.99, and α = −0.2 K. Suitable geometry of one-dimensional hydrogen-bonded chains of (I) results in a positive J value, which indicates ferromagnetic interaction. On the other hand, compounds (II) and (III) show antiferromagnetic interaction, indicating typical Curie–Weiss behaviour. The Weiss constants for (II) and (III) are −9.04 K and −0.37 K, respectively. We attempted to analyse the data for (III) to obtain J. However, in contrast with many dimers, it is difficult to fit, because there is no inflection point in the plot of ueff versus T. Also, the treatment of the molecular field approximation is unclear. The diffuse reflectance spectra at 294 K support the 5B1 g ground state of the MnIII ion (S = 2) for (I)–(III).
In addition, we irradiated the crystals with UV and visible light at 8 K, which resulted in a reversible change of the IR band intensity around 3100 cm−1 (O—H band) for the axial ligands for (I)–(III). In contrast with the analogous CuII complex (Akitsu & Einaga, 2004), photo-irradiation did not affect the axial Jahn–Teller distortion for the three rigid MnIII complexes, (I)–(III).
