A novel organotin complex of μ-pentaoxygen bridged penta(bis-benzyltin) bis- salicylate has been synthesized by the reaction of bis-benzyltin oxide and salicylic acid and its struc- ture has been determined by X-ray diffraction. The crystal belongs to monoclinic, space group P21/n with a = 1.7206(5), b = 2.1401(6), c = 2.1488(6) nm, β = 93.325(5)°, V = 7.899(4) nm3, Z = 4, Dc = 1.564 g/cm3, μ(MoKα) = 16.17 cm?1, Mr = 1859.94, F(000) = 3692, R1 = 0.0755 and wR2= 0.1557. According to structural analysis, the coordination geometry of tin is a distorted trigonal bipyramid, and the ladder-like structure is shaped by four Sn2O2 planar four-membered rings.
