Özet

In the centrosymmetric title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)]center dot 2H(2)O, the CuII ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methylbenzoate anion, one isonicotinamide (INA) ligand and one uncoordinated water molecule; all the ligands are monodentate. The two O and the two N atoms around the CuII ion form a slightly distorted square-planar arrangement. The dihedral angle between the carboxylate group and the attached benzene ring is 13.86 (9)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 86.08 (5)degrees. The uncoordinated water molecules are linked to the INA ligands by O-H...O hydrogen bonds. In the crystal structure, intermolecular O-H...O, N-H...O and C-H...O hydrogen bonds link the molecules into a three-dimensional network.
