An anhydrous ethanol solution (50 ml) of 4-hydroxy-3-iodo-5-methoxy- benzaldehyde (2.78 g, 10 mmol) was added to an anhydrous ethanol solution (50 ml) of 4-amino-1,5-dimethyl-2-phenyl-pyrazolidin-3-one (2.03 g, 10 mmol) and the mixture was stirred at 350 K for 6 h under N2, whereupon a colorless solution appeared. The solvent was removed and the residue recrystallized from anhydrous ethanol. The product was isolated and then dried in vacuo to give the title compound in 75% yield. Colorless single crystals suitable for X-ray analysis were obtained by slow evaporation of an anhydrous ethanol solution.
The 4-hydroxy-3-iodo-5-methoxybenzene group is disordered over two positions with a site occupancy ratio of 0.907 (2):0.093 (2). In the disordered group, the C(phenyl)-O, C(methyl)-O and C—I distances were restrained to 1.35 (1), 1.45 (1) and 2.10 (1) Å, respectively, and the C and O atoms of the minor component were refined isotropically. The N-bound H atom was located in a difference Fourier map and its positional parameters were refined, with Uiso(H) = 1.2Ueq(N). C– and O-bound H atoms were included in calculated positions (C—H = 0.95–0.98 Å and O—H = 0.84 Å), and refined using a riding model, with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O).
In order to establish control over the preparation of crystalline solid materials so that their architecture and properties are predictable (Belloni et al., 2005; Tynan et al., 2005; Parashar et al., 1988), the synthesis of new and designed crystal structures has become a major strand of modern chemistry. Metal complexes based on Schiff bases have attracted much attention because they can be utilized as model compounds of active centres in various proteins and enzymes (Kahwa et al., 1986; Santos et al., 2001). As part of an investigation of the coordination properties of Shiff bases functioning as ligands, we report the synthesis and structure of the title compound, (I). In the molecular structure of the title compound (Fig. 1), the expected geometric parameters are observed. The central chomophore (C8—C10/N2/N3) is planar, with an r.m.s. deviation for the fitted atoms of 0.0287 (2) Å. The C8—C10/N2/N3 ring makes dihedral angles of 5.66 (6) and 54.94 (5)° with the benzene C1—C6 and phenyl C13—C18 rings, respectively. The C1—C6 and C13—C18 rings are inclined at an angle of 49.77 (4)°. There are intramolecular O—H···O and C—H···O hydrogen bonds which stabilize the molecular structure. The molecules are linked via a weak intermolecular O—H···O hydrogen bond (Fig. 2). A short intermolecular I···O contact is observed [I1···O2(x,-1/2 - y,1/2 + z) 3.156 (4) Å].

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In order to establish control over the preparation of crystalline solid materials so that their architecture and properties are predictable (Belloni et al., 2005; Tynan et al., 2005; Parashar et al., 1988), the synthesis of new and designed crystal structures has become a major strand of modern chemistry. Metal complexes based on Schiff bases have attracted much attention because they can be utilized as model compounds of active centres in various proteins and enzymes (Kahwa et al., 1986; Santos et al., 2001). As part of an investigation of the coordination properties of Shiff bases functioning as ligands, we report the synthesis and structure of the title compound, (I). In the molecular structure of the title compound (Fig. 1), the expected geometric parameters are observed. The central chomophore (C8—C10/N2/N3) is planar, with an r.m.s. deviation for the fitted atoms of 0.0287 (2) Å. The C8—C10/N2/N3 ring makes dihedral angles of 5.66 (6) and 54.94 (5)° with the benzene C1—C6 and phenyl C13—C18 rings, respectively. The C1—C6 and C13—C18 rings are inclined at an angle of 49.77 (4)°. There are intramolecular O—H···O and C—H···O hydrogen bonds which stabilize the molecular structure. The molecules are linked via a weak intermolecular O—H···O hydrogen bond (Fig. 2). A short intermolecular I···O contact is observed [I1···O2(x,-1/2 - y,1/2 + z) 3.156 (4) Å].
