Diaqua­bis­(4-formyl­benzoato-κO (1))bis­(nicotinamide-κN (1))copper(II)

In the title complex, [Cu(C(8)H(5)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) 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.
