In the title compound, [Cd(SO₄)(C₁₂H₈N₂)₂]·C₃H₈O₂, the Cd^II atom has a distorted octahedral coordination composed of four N atoms from two chelating 1,10-phenanthroline ligands and two O atoms from an O,O′-bidentate sulfate group. The two chelating NCCN groups subtend a dihedral angle of 82.21 (9)°. The Cd^II ion, the S atom and the middle C atom of the propane-1,3-diol solvent molecule are located on special positions, site symmetry 2. The solvate features a pair of O—H⋯O hydrogen bonds with the uncoordinated O atoms of the sulfate ion. The OH group of the propane-1,3-diol solvent is disordered over two positions of equal occupancy.

Comment top

The design and synthesis of new coordination polymers have attracted great attention in recent years, owing to their interesting structural topologies and potential application as functional materials (Batten & Robson,1998; Eddaoudi et al., 2001; Li et al., 2003). Four years ago, we attempted to synthesize mixed-ligand coordination polymers of transition metal with phen as second ligand via a ethanediol-solvothermal reaction, unexpectedly, we found the potentially interesting structure with bidentate-chelating sulfate ligand, e.g. [CdSO₄(C₁₂H₈N₂)₂].C₂H₆O₂, (II) (C₁₂H₈N₂ is 1,10- phenanthroline; Lu et al., 2006), [CoSO₄(C₁₂H₈N₂)₂].C₂H₆O₂, (III) (Zhong et al.,, 2006), [ZnSO₄(C₁₂H₈N₂)₂].C₂H₆O₂, (IV) (Zhu et al., 2006). We report here the structure of [CdSO₄(C₁₂H₈N₂)₂].C₂H₆O₂, (I).

X-ray diffraction indicated that the title compound, (I) is isostructural to the recently reported cobalt(II), nickel(II) and zinc(II) structure with bidentate-chelating sulfate ligand (Zhong, 2010; Cui et al., 2010; Ni et al., 2010). The geometry of the phen and sulfate ligands is in good agreement with those reported in the three isomorphs complexes. The Cd^II metal ions has an octahedral coordination environment, with four N atoms from two phen ligands and two O atoms from a O,O'-bidentate sulfate group. The Zn^II ion, S atom and the mid-carbon atom of the propane-1,3-diol solvent molecule lie on a special position of site symmetry 2 [symmetry code: -x + 1, y, - z + 1/2]. The dihedral angle (82.2°) between the two chelating NCCN groups are larger than that found in (II) [74.5°; Lu et al., 2006]. The Cd—N bond distance [2.3258 (19)–2.3441 (19) Å], the N—Cd—N bite angle [72.00 (7)°], the O—Cd—O bite angle [60.39 (8)°] and the Cd—O bond distance [2.3605 (17) Å] are are in good accord with those found in the (II) [71.91 (7)°, 2.327 (2)–2.343 (2) Å, 59.98 (9)° and 2.361 (2) Å, respectively]. Selected coordination bond distances and angles in Table 1. In the crystal structure, a pair of intermolecular O—H···O hydrogen bonds help to further stabilize structure (see Fig. 1 and Table 2).

Fig. 2 shows the crystal packing of the title compound. The molecular twofold axis is along the direction of the molecular dipole moment and the complexes are packed with their dipole moments alternately along the b axis directions.

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.
