Poly[[(μ2‐biphenyl‐2,4′‐dicarboxylato)[μ2‐1,4‐bis(imidazol‐1‐ylmethyl)benzene]cadmium(II)] 0.15‐hydrate]

The asymmetric unit of the title two-dimensional coordination polymer, {[Cd(C14H8O4)(C14H14N4)]·0.15H2O}n, is composed of one CdII cation, one biphenyl-2,4′-dicarboxyl­ate (bpdc) anion, one 1,4-bis­(imidazol-1-yl­methyl)­benzene (bix) ligand and 0.15 solvent water mol­ecules. The coordination environment of the CdII cation is defined by four carboxyl­ate O atoms from two different bpdc anions in a chelating mode and two N atoms from two distinct bix ligands, constructing a distorted trigonal prism polyhedron. Two inversion-related CdII cations are bridged together by two positionally disordered bpdc anions, forming a 22-membered ring with a Cd⋯Cd distance of 9.1966 (9) A. These rings are then further linked by two bix ligands, extending into a two-dimensional layer along (102) with 63 topology.
