Synthesis, Characterization and Crystal Structure of (PhCH2)2Sn-(S2CNEt2)2and (PhCH2)2Sn(S2CNC4H8)2

Two new dibenzyltin bisdithiocarbamates (PhCH2)2Sn(S2CNEt2)2 (1) and (PhCH2)2Sn(S2CNC4H6)2 (2) were synthesized by the reaction of dibenzyltin dichloride with dithiocarbamates and characterized by elemental analysis, IR, 1H NMR and MS spectra. The crystal structures were determined by X-ray single crystal diffraction analysis. In both complexes, the tin atom is six-coordinated in a distorted octahedral configuration. In the crystals of 1, the molecular packing in unit cell reveals that the two adjacent molecules are symmetrically linked to each other in dimers by two Sn … S interactions of 0.3816 nm. In the crystals of 2, the molecules are packed in the unit cell in one-dimensional chain structure linked by weaker intermolecular S … S contacts.
