A one-dimensional coordination polymer: catena-poly[[diaqua(2,4-dihydroxybenzoato)cadmium(II)]--2,4-dihydroxybenzoato]

Z.-L. Wang and Y.-P. Niu

Abstract: The title compound, [Cd(C₇H₅O₄)₂(H₂O)₂]_n, consists of a one-dimensional chain, in which the Cd²⁺ centre is coordinated by four O atoms from two bidentate carboxylate groups of two 2,4-dihydroxybenzoate anions, two water molecules, and one hydroxyl O atom of another 2,4-dihydroxybenzoate anion. This results in a distorted pentagonal-bipyramidal CdO₇ polyhedron.
