Poly[[bis[μ-1,2-bis(4-pyridyl)ethene]-bis(trichloroacetato)cadmium(II)] monohydrate]

Abstract

In the crystal structure of the title compound, {[Cd(C2Cl 3O2)2- (C12H10N 2)2]·H2O}n, the CdII ion lies on a twofold rotation axis and 1,2-bis(4-pyridyl)ethene ligands bridge symmetryrelated CdII ions, forming a two-dimensional structure. Two trichloroacetate ligands complete the coordination around the CdII ion, forming a distorted octahedral environment. In the crystal, solvent water molecules, which also lie on twofold rotation axes, form intermolecular O - H⋯O hydrogen bonds, which connect the two-dimensional structure into a three-dimensional network. The crystal studied was an inversion twin, the refined ratio of twin components being 0.75 (4):0.25 (4).
