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.
