The crystal structure of the title complex has been determined by single crystal X ray diffraction techniques. The crystal belongs to monoclinic with space group P21/c. The cell parameters are: a=1.6362(9)nm, b=1.7140(9)nm, c=1.2255(7)nm, β=105.168(9)°, V=3.317(3)nm3, Z=8, Dc=1.525g·cm-3, μ(MoKα)=1.334mm-1, F(000)=1560. The structure wasrefined to final R1=0.0376, wR2=0.0909. The copper?ion lies in a distorted square planar environment composed of two oxygen atoms, one nitrogen atom of tridentate acyhydrazone Schiff base ligand and one nitrogen atom of the pyridine ligand.

The novel seven coordinate complex [(n Bu)2Sn(C10H8N2O3)(C2H5OH)]2 (C10H8N2O32- is the dinegative ion of 2 oxo propionic acid benzoyl hydrazone) was synthesized by the reaction of (n Bu)2SnO with 2 oxo propionic acid ...The novel seven coordinate complex [(n Bu)2Sn(C10H8N2O3)(C2H5OH)]2 (C10H8N2O32- is the dinegative ion of 2 oxo propionic acid benzoyl hydrazone) was synthesized by the reaction of (n Bu)2SnO with 2 oxo propionic acid benzoyl hydrazone in 1∶ 1 molar ratio in benzene ethanol (V/V, 3/1), and its structure was characterized by X ray single crystal diffraction. The crystal belongs to a tetragonal system with space group I41/a, a=2.4890(2)nm, b=2.4890(2)nm, c=1.5170(3)nm, V=9.398(2)nm3, Z=8, F(000)=3968, Dc=1.366g· cm- 3, and the structure was refined to final R1=0.0530, wR2=0.0971. The structure of the title complex is described as a dimer through weak interactions of Sn… O bonding and hydrogen bond. The tin atoms rendered seven coordination in a distorted pentagonal bipyramid geometry structure, four oxygen atoms [O1, O2, O2# 1 and O4] and one nitrogen atom N2 formed the equatorial plane and C11 Sn1 C15 is the axis.
