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

Abstract

The title CdII coordination polymer, catena-poly[[{1,4-bis[1-(2-pyridylmethyl)benzimidazol-2-yl]butane}cadmium(II)]-μ-benzene-1,3-dicarboxylato], [Cd(C8H4O4)(C30H28N6)]n, was obtained by reaction of CdCO3, benzene-1,3-dicarboxylic acid (H2btc) and 1,4-bis[1-(2-pyridylmethyl)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].
