Diaqua­Bis­(4-Formyl­Benzoato-Κo 1)Bis­(Nicotinamide-Κn1)Copper(Ii)

Abstract

In the title complex, [Cu(C8H5O3)2(C6H6N2O)2(H2O)2], the CuII cation is located on an inversion center and is coordinated by two 4-formyl­benzoate (FB) anions, two nicotinamide (NA) ligands and two water mol­ecules in an elongated distorted octa­hedral geometry. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 23.00 (10)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 85.34 (4)°. An intra­molecular O—H⋯O hydrogen bond occurs between coordinating water mol­ecule and the carboxyl­ate group. In the crystal, N—H⋯O, O—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional supra­molecular network. A weak C—H⋯π inter­action also occurs in the crystal.
