Özet
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. ?-? 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)°.
