Aquabis(3-chlorobenzoato-?O)bis(N,N-diethylnicotinamide-?N) copper(II)

The title compound, [Cu(C7H4ClO2)2(C10H14N2O)2(H2O)], has twofold symmetry with the CuII cation and the O atom of the coordinating water molecule located on the axis. The CuII cation is coordinated by two carboxylate O atoms of chlorobenzoate (CB) anions, two N atoms of N,N-diethylnicotinamide (DENA) ligands and one water molecule in a distorted N2O3 square-pyramidal geometry. The benzene and pyridine rings are oriented at a dihedral angle of 82.51 (6)°. In the anionic ligand, the carboxylate group is twisted away from the attached benzene ring by 12.85 (11)°. In the crystal, O - H?O hydrogen bonds between the coordinating water molecule and the carboxyl group link the complex molecules into supramolecular chains running along the c-axis direction.
