Catena-Poly[[aqua-bis-(3-chloro-benzoato-?(2) O,O')cadmium]-?-N,N-di-ethyl-nico-tin-amide-?(2) N (1):O].

ABSTRACT: In the crystal of the title Cd(II) polymeric complex, [Cd(C7H4ClO2)2(C10H14N2O)(H2O)] n , the Cd(II) cation is chelated by two chloro-benzoate anions and coordinated by two N,N-di--ethyl-nicotinamide (DENA) ligands and one water mol-ecule in a distorted NO6 penta-gonal-bipyramidal geometry. The Cd(II) 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. Inter-molecular O-H?O hydrogen bonds between coordinating water mol-ecules and carboxyl-ate 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 mol-ecule, weak C-H?O hydrogen bonds occur between the pyridine ring and carboxyl-ate groups; the dihedral angles between the carboxyl-ate 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)°.
