Abstract top

In the title polymer, [Cd(C16H10O4)(C10H8N2)(H2O)]n, the CdII ion is in a strongly distorted octahedral geometry, being coordinated by two N atoms from a 2,2'-bipyridine ligand, three carboxylate O atoms from two symmetry-related trans-stilbene-4,4'-dicarboxylate dianions and one water molecule. The stilbene ligand lies on an inversion centre at the midpoint of the central C=C bond. This feature generates the polymeric structure: adjacent CdII ions are bridged by trans-stilbene-4,4'-dicarboxylate dianions, giving rise to a one-dimensional structure. The coordinated water molecule is involved in interchain O-H...O hydrogen bonds.

Comment top

We are interested in the solid-state coordination chemistry of trans-stilbene-4,4'-dicarboxylic acid, combined with specific transition metal ions, to fabricate versatile coordination polymers. In our previous work, a one-dimensional NiII-organic framework had been reported (Wang et al., 2006). In order to further explore the behavior of trans-stilbene-4,4'-dicarboxylic acid as ligand, a new one-dimensional CdII complex has been obtained and characterized.

The molecular structure of the title compound is illustrated in Fig. 1. The CdII ion is in a strongly distorted octahedral geometry and is coordinated by two N atoms of a 2,2'-bipyridine ligand, three carboxyl O atoms of two symmetry-related trans-stilbene-4,4'-dicarboxylato dianions, which adopted two different coordination modes, and one water molecule. One of the two carboxylic ligands is found in the bis-monodentate mode, and the other in the chelating bis-bidentate mode, linking the adjacent CdII ions into a zigzag chain structure. In addition, the chains are interconnected through intermolecular hydrogen bonds involving water molecules, and π–π interactions involving 2,2'-bipyridine ligands, [centroid-to-centroid separation: 3.8749 (10) Å], forming a three-dimensional supramolecular network (Table 2 and Fig. 2).

A closely related NiII complex with 1,10-phenanthroline and the trans-stilbene-4,4'-dicarboxylate dianion as ligands has been characterized by X-ray diffraction (Wang et al., 2006).

Experimental top

A mixture of CdCl2.6H2O (1 mmol), 2,2'-bipyridine (1 mmol), trans-stilbene-4,4'-dicarboxylic acid (1 mmol) and water (10 ml) was stirred for 15 min. in air, then transferred and sealed in a 23 ml Parr teflon-lined stainless steel vessel, heated to 433 K for 5 days, and then cooled to room temperature. The resulting colorrless crystals were filtered, washed, and dried in air. Analysis calculated for C26H20CdN2O5: C 56.31, H 3.64, N 5.05%; found: C 56.34, H 3.62, N 5.03%.

Refinement top

Water H atoms were located in a difference map and refined with O—H and H···H distances restrained to 0.85 (1) and 1.39 (1) Å, respectively, and Uiso(H) = 1.5Ueq(O1W). All other H atoms were placed in calculated positions with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(carrier C), and were refined in the riding-model approximation.
