Synthesis, Crystal Structure and Quantum Chemical Study of the Ladder Organotin Compound {（C6H5CH2）2Sn2（O）（Cl2）}2

摘要

cqvip:The title compound {[(C6H5CH2)2Sn]2(O)(Cl2)}2 has been synthesized by the reaction of bisbenzyltin dichloride with NaOH dilute solution, and its structure was determined by X-ray diffraction. The crystal belongs to monoclinic, space group C2/c, with a = 2.5081(17), b = 1.0089(7), c = 2.0909(14) nm, β = 94.267(8)°, V = 5.276(6) nm3, Z = 4, Dc = 1.734 g/cm3, μ(MoKa) = 21.55 cm-1, F(000) = 2704, R = 0.0398 and Rw = 0.1024. According to structural analysis, the tin atom adopts a distorted five-coordinate trigonal bipyramidal geometry, and the ladder-like structure is shaped by one planar four-membered Sn2O2 ring together with two planar four-membered Sn2OCl rings.
