A novel organotin hydration dibenzyltin dichloride has been synthesized and its crystal structure was determined by X-ray diffraction. The crystal belongs to monoclinic, space group Pc with a = 1.1918(5), b = 0.6199(2), c = 1.1074(5) nm, β = 106.899(7)°, V= 0.7828(8) nm3, Z = 2, Dc = 1.654 g/cm3, μ(MoKa) = 19.59 cm-1, F(000) = 384, R = 0.0564 and RwR = 0.1427. The Sn-C bonds are 0.2140(9) and 0.2152(5) nm, Sn-Cl are 0.2385(4) and 0.2497(3) nm, and Sn-0 is 0.2388(7) nm. The tin atom is five-coordinated in a distorted trigonal bipyramidal conf...
