abstract
The asymmetric unit of the title compound, {[Ce(C3H2O4)Cl-(H2O)(3)]center dot 0.5H(2)O}(n), contains a Ce3+ atom coordinated by a chloride anion, three water molecules and a malonate ligand, and one water molecule of crystallization with a factor of occupancy of 50%. The malonate ligand is bonded to three different symmetry-related metal atoms yielding a one-dimensional coordination polymer running parallel to the a axis. A supramolecular network composed of strong and highly directional O-H center dot center dot center dot O and O-H center dot center dot center dot Cl hydrogen bonds ensures a close and effective packing of adjacent polymeric chains.
