R factor = 0.018; wR factor = 0.041; data-to-parameter ratio = 16.3. The title compound, [CdCl2(C9H11NO2)]n, is a coordination polymer prepared by the hydrothermal reaction of cadmium(II) chloride and 3-amino-3-phenylpropanoic acid. Geometric parameters are in the usual ranges. The cadmium cation is octahedrally coordinated by four Cl atoms at equatorial sites and two O atoms from two ligands at the axial sites. The material is composed of one-dimensional extended polymeric chains in which two Cl atoms bridge Cd atoms. The crystal structure is stabilized by an intramolecular N—H ��� O hydrogen bond.
