Abstract

In the crystal structure of the title centrosymmetric dimer, [Cu(2)(C(17)H(14)N(2)O(2))(2)(C(5)H(5)N)(2)], the Cu(II) atom has an almost perfect square-pyramidal geometry. The Cu(II) ion is coordin-ated by the NO(2) donor atoms of the hydrazide Schiff base ligand, the N atom of the pyridine group and an O atom of the symmetry-related unit. The dihedral angles between the pyridine ring and the two phenyl rings of the ligand are 21.4 (3) and 24.0 (2)°. The mol-ecular structure is stabilized by intra-molecular C-H⋯O inter-actions.
