The one-dimensional polymer poly[[aqua(2,2′-bipyridine)cadmium(II)]-μ-trans-stilbene-4,4′-dicarboxylato]
Abstract
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.
