Abstract: In the crystal of the title CdII polymeric complex, [Cd(C7H4ClO2)2(C10H14N2O)(H2O)]n, the CdII cation is chelated by two chloro­benzoate anions and coordinated by two N,N-di­­ethyl­nicotinamide (DENA) ligands and one water mol­ecule in a distorted NO6 penta­gonal-bipyramidal geometry. The CdII cations are bridged by the pyridine N atom and carbonyl O atom of the DENA ligand to form a polymeric chain running along the b axis. Inter­molecular O-H...O hydrogen bonds between coordinating water mol­ecules and carboxyl­ate groups link adjacent chains into layers parallel to the bc plane. [pi]-[pi] contacts between benzene rings [shortest centroid-centroid distance = 3.912 (2) Å] further stabilizes the crystal structure. In the mol­ecule, weak C-H...O hydrogen bonds occur between the pyridine ring and carboxyl­ate groups; the dihedral angles between the carboxyl­ate groups and adjacent benzene rings are 4.6 (3) and 12.8 (3)°, while the benzene rings are oriented at a dihedral angle of 1.89 (13)°.
