n, the asymmetric unit contains a crystallographically unique Cd
II atom, one doubly deprotonated 4,4'-sulfonyldibenzoic acid (H
2SDBA) ligand, one 3,4,7,8-tetramethyl-1,10-phenanthroline (TMPHEN) molecule and three solvent water molecules. Each Cd
II centre is six-coordinated by two O atoms from a chelating carboxylate group of a SDBA
2- ligand, two O atoms from monodentate carboxylate groups of two different SDBA
2- ligands and two N atoms from a chelating TMPHEN ligand. There are two coordination patterns for the carboxylate groups of the SDBA
2- ligand, with one in a
1-

1 chelating mode and the other in a
2-

1 bis-monodentate mode. Single-crystal X-ray diffraction analysis revealed that the title compound is a one-dimensional double-chain polymer containing 28-membered rings based on the [Cd
2(CO
2)
2] rhomboid subunit. More interestingly, a chair-shaped water hexamer cluster is observed in the compound.

A mixture of Cd(NO3)2.6H2O (34.5 mg, 0.1 mmol), H2SDBA (30.6 mg, 0.1 mmol), TMPHEN (35.4 mg, 0.15 mmol) and NaOH (6.0 mg, 0.15 mmol) in H2O (10 ml) was sealed in a 16 ml Teflon-lined stainless steel container and heated at
453 K for 72 h. After cooling to room temperature, white block-shaped crystals
of (I) were collected by filtration and washed water water and ethanol several
times (yield 7.3%, based on H2SDBA). Elemental analysis for
C30H30CdN2O9S: C 50.96, N 3.96, H 4.28%; found: C 51.08, N 3.97, H
4.31%.
H atoms bonded to C atoms were placed in calculated positions and treated using
a riding-model approximation, with C—H = 0.95 Å and Uiso(H) =
1.2Ueq(C) for aromatic H atoms, and C—H = 0.98 Å and
Uiso(H) = 1.2Ueq(C) for the tert-butyl H atoms. Water
H atoms were located in difference Fourier maps and were refined with a
distance restraint of O—H = 0.85 Å and with Uiso(H) =
1.5Ueq(O).

Special details top
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. |

The design and synthesis of metal–organic compounds has been flourishing in recent years, not only due to their diverse topology and intriguing structures but also owing to their potential applications in areas such as gas storage, ion exchange and catalysis (Kitagawa et al., 2004; Ferey et al., 2005; Roy et al., 2009; Zhang et al., 2009; Jiang et al., 2009). It is well known that the construction of metal–organic compounds is usually influenced by several factors in the self-assembly process, such as the solvent system, temperature, the organic ligands and the metal atoms (Kan et al., 2012; Liu et al., 2012). Among these factors, the organic ligands play a key role in determining the final architectures. The main method for constructing coordination polymers is to utilize carboxylate-containing ligands, since the carboxylate groups have an excellent coordination capability and flexible coordination patterns. As an important family of multidentate O-donor ligands, semi-rigid V-shaped dicarboxylate ligands, such as 4,4'-oxybis(benzoic acid) (H2OBA), 4,4'-(hexafluoroisopropylidene)bis(benzoic acid) (H2FA), 4,4'-sulfonyldibenzoic acid (H2SDBA), have been used extensively in constructing new metal–organic compounds (Zhuang et al., 2007; Lian et al., 2008; Xiao et al., 2008; Chen et al., 2009; Liu et al., 2009; Li et al., 2010). However, to the best of our knowledge, coordination polymers constructed from 4,4'-sulfonyldibenzoic acid (H2SDBA) and 3,4,7,8-tetramethyl-1,10-phenanthroline (TMPHEN) ligands have not been reported so far. We report here the structure of the CdII coordination polymer {[Cd(SDBA)(TMPHEN)].3H2O}n, (I) (Fig. 1).
Compound (I) crystallizes in the monoclinic space group P21/c, and the asymmetric unit contains a crystallographically unique CdII atom, one fully deprotonated H2SDBA ligand, one TMPHEN molecule and three solvent water molecules. Each CdII centre is six-coordinated by two O atoms from a chelating carboxylate group of a SDBA2- ligand, two O atoms from monodentate carboxylate groups of two different SDBA2- ligands and two N atoms from a chelating TMPHEN ligand (Table 1). The average Cd—O and Cd—N distances (Table 1) in (I) are comparable with those in other reported CdII-based compounds (Wang et al., 2011, 2012).
In the SDBA2- ligand in (I), the dihedral angle between the two benzene rings is 86.0 (3)° and the C23–S1–C24 angle is 104.8 (2)°. The dihedral angles between the carboxylate groups and their adjacent benzene rings are 159.8(s.u.?) and 6.2(s.u.?)°. It is worth noting that the SDBA2- ligand links three CdII atoms and there are two coordination patterns for the carboxylate groups, with one in a µ1-η1:η1 chelating mode and the other in a µ2-η1:η1 bis-monodentate mode. Two crystallographically equivalent CdII atoms are bridged by atoms O5, O6 and C30 to form a binuclear [Cd2(CO2)2] motif; the Cd···Cd separation is 3.1383 (7) Å. The [Cd2(CO2)2] rhomboid subunit is further bridged by an SDBA2 ligand into a one-dimensional double chain containing 28-membered rings, with SDBA2- ligands as bridges arranged parallel to the a direction (Fig. 2). The TMPHEN ligands are extended on both sides of the chain. In addition, the chains are connected by two types of the hydrogen bonds (O—H···O and C—H···O) and by π–π and S═O···π interactions to form a three-dimensional supramolecular structure (Fig. 3). Approximately 12.2% of the crystal volume is occupied by the solvent molecules, with a volume of ~353.0 Å3 in each unit cell (2883.4 Å3), based on a PLATON calculation (Spek, 2009).
Interestingly, six lattice water molecules [O7, O7v, O8, O8v, O9 and O9v; symmetry code: (v) -x+1, -y+1, -z+1] related by a twofold axis form a chair-shaped water hexamer via hydrogen bonds (Table 2). The average O···O distance within the hexamer is 2.96 Å, which is significantly longer than the corresponding value of 2.85 Å in liquid water. The O···O···O angles range from 63.7(s.u.?) to 125.9(s.u.?)°, deviating considerably from the preferred ideal tetrahedral geometry of water (Fig. 4). Such hexamers are fixed to the framework through numerous hydrogen bonds involving solvent water O atoms and carboxylate (O2 and O5) and sulfonyl (O3 and O4) O atoms.
In conclusion, we have synthesized a one-dimensional double-chain polymer containing 28-membered rings based on the [Cd2(CO2)2] rhomboid subunit. More interestingly, there exists a chair-shaped water hexamer cluster.
