The n-butyl alcohol solution of p-cyanobenzyl chloride and Sn was heated at reflux for 6h to yield the tri(p-cyanobenzyl) tin chloride. The crystal and molecular structures of compound was determined by X-ray diffraction. The crystal is triclinic, space group P (1) over bar with a = 0.9706(3) nm, b = 0.9882(3) nm, c = 1.3916(4) nm, V = 1.1081nm(3), Z = 1, D-x = 1.506Mg (.) m(-3), mu(MoKalpha) = 12.88cm(-1), F(000) = 500. R-1 = 0.0320, wR(2) = 0.0695. The bond lengths of Sn-C is 0.2152 similar to 0.2164nm. The Sn-Cl is 0.24088nm. The t...
