Synthesis and characterization of chlorodibenzyltin(IV) complexes with N,N-dialkyl dithiocarbamate ligands and crystal structure of (PhCH2)2SnCl(S2CNMe2)

Thirteen chlorodibenzyltin(IV) complexes with N,N-dialkyl dithiocarbamate ligands have been synthesized by the reaction of dibenzyltin dichloride with N,N-dialkyl dithiocarbamates in 1: 1 stoichiometry and characterized by elemental analysis, UV, IR and H-1 NMR. The crystal structure of (PhCH2)(2) SnCl(S2CNMe)(2) has been determined by X-ray single crystal diffraction. The crystallographic data are as follows: triclinic, space group P-1, a=7.5750(15) Angstrom, b=10.615(2) Angstrom, c=12.059(2) Angstrom, alpha=95.053(3)degrees, beta=95.539(4)degrees, gamma=99.113(4)degrees, Z=2, V=947.6(3) Angstrom, Dx=1.600g/cm(-3), mu=1.705mm(-1), F(000)=456, R-1=0.0409, wR(2)=0.1194(Igreater than or equal to2sigma(I). The structures consist of discrete molecules containing five-coordinate tin atoms in a seriously distorted trigonal bipyramidal configuration. The molecules are packed in the unit cell as weakly-bridged dimers.
