title: Poly[(μ3-benzene-1,4-dicarboxylato)di-μ-chlorido-(triethanolamine)dicadmium(II)]: a cadmium-halide coordination polymer with a hydrogen-bonded three-dimensional framework.
abstract: The structure of the title compound, [Cd(2)(C(8)H(4)O(4))Cl(2)(C(6)H(15)NO(3))](n), consists of one-dimensional chains in which each centrosymmetric tetranuclear Cd(4)Cl(4)O(2) cluster is terminated by two chelating triethanolamine (teaH(3)) ligands but linked to two adjacent clusters through four bridging benzene-1,4-dicarboxylate (bdc) ligands. The tetranuclear Cd(4)Cl(4)O(2) clusters are held together via bridging Cl and O atoms. Three directional hydrogen bonds from the multi-podal hydroxy groups of the teaH(3) ligand stabilize and extend the one-dimensional chains into a three-dimensional framework. All three hydroxy groups of the teaH(3) ligand form hydrogen bonds, illustrating the fact that the teaH(3) ligand can serve as an excellent hydrogen-bond donor.
