A coordination polymer of CdII with benzene-1,3-dicarboxyl-ate and 1,4-bis-[1-(2-pyridylmeth-yl)benzimidazol-2-yl]butane

Abstract

The title CdII coordination polymer, catena-poly[[{1,4-bis-[1- (2-pyridylmeth-yl)benzimidazol-2-yl]butane}cadmium(II)]- benzene-1,3-dicarboxyl- ato], [Cd(C8H4O4)(C30H 28N6)] n , was obtained by reaction of CdCO3, benzene-1,3-dicarboxylic acid (H2btc) and 1,4-bis-[1-(2-pyridylmeth-yl) benzimidazol-2-yl]butane (L). The CdII cation is six-coordinated by an N2O4-donor set. L acts as a bidentate ligand and btc anions link CdII centers into a chain propagating parallel to [010].
