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.
