Abstract
In the title polymer, [Cd(C8H10O4)(H2O)2]n, the CdII cation is coordinated by five carboxylate O atoms from three different cyclohexane-1,2-dicarboxylate anions and two O atoms from two water molecules, displaying a distorted CdO7 pentagonal–bipyramidal geometry. Each anion acts as a μ3-bridge, linking symmetry-related CdII ions into a layer parallel to (010). In the crystal, numerous O—H...O and C—H...O hydrogen bonds occur. The coordinated water molecules and carboxylate O atoms act as donors or acceptors in the formation of these hydrogen-bonding interactions.
