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

Abstract

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, I R and ¹H NMR. The crystal structure of (PhCH₂)₂SnCl(S₂CNMe₂) has been determined by X-ray single crystal diffraction. The crystallographic data are as follows: triclinic, space group P-1,

<i>a</i>=7.5750(15) Å, <i>b</i>= 10.615(2) Å, <i>c</i>= 12.059(2) Å, α=95.053(3)^o,

β=95.539(4)^o, γ=99.113(4)^o, Z=2, <i>V=</i>947.6(3)<i> </i>Å, <i>Dx= </i>1.600<i>g/</i>cm^-3, μ= 1.705mm^-1, <i>F</i>(000)<i>=</i>456<i>, R</i>₁<i>=</i>0.0409, <i>w</i>R₂=0. 1194(I≥ ~2σ(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.
