摘  要:The title complex {[(C6H5CH2)4Sn2(OOCC9H11)(ONHCH2C6H5)]O}2 (CgH11COO = 2,4,6- trimethyibenzolicate) has been synthesized by the reaction of bis-benzyitin oxide with 2,4,6-trimethyibenzolic acid and N-benzyihydroxylamine in 1:1:1 molar radio (C45H47NO4Sn2) and characterized by IR, ^1H NMR spectra and elemental analysis, and its crystal structure was determined by X-ray diffraction. It crystallizes in monoclinic, space group P21/c with α = 1.5654(5), b = 1.6467C6), c = 1.7433C6) nm, β = 111.729C5)°, Z = 2, V = 4.175C2) nm^3, Mr = 903.22, Dc = 1.437 g/cm^3,μ = 1 .238 mm^-1, F(000) = 1824, R = 0.0440 and wR = 0.0906. The structure shows that the central tin atom is five-coordinated to assume a distorted trigonai bipyramidai configuration. The compound belongs to centrosymmetric dimer structure with four-membered central endo-cyclic Sn202 units in which the bridging oxygen atoms are tri-coordinated.The title complex {[(C6H5CH2)4Sn2(OOCC9H11)(ONHCH2C6H5)]O}2 (CgH11COO = 2,4,6- trimethyibenzolicate) has been synthesized by the reaction of bis-benzyitin oxide with 2,4,6-trimethyibenzolic acid and N-benzyihydroxylamine in 1:1:1 molar radio (C45H47NO4Sn2) and characterized by IR, ^1H NMR spectra and elemental analysis, and its crystal structure was determined by X-ray diffraction.
