Synthesis, Spectroscopic Properties and Crystal Structures of Dibenzyltin(Ⅳ) Dithiobenzoate and Chlorodibenzyltin(Ⅳ) Thiobenzoate

摘要

Two dibenzyltin(Ⅳ) complexes with thiobenzoate ligand, (PhCH_2)_2Sn(SOCPh)_2 (1) and (PhCH_2)_2Sn(Cl)SOCPh (2), have been synthesized by the reaction of dibenzyltin(Ⅳ) dichloride with thiobenzoic acid in the presence of organic base Et_3N and characterized by IR, ~1H NMR spectroscopy and elemental analysis. Their crystal structures were determined by X-ray single crystal diffraction analysis. In the crystals of 1, the tin atom is six-coordinated in a distorted octahedron configuration. In the crystals of 2, the molecular packing in unit cell reveals that the two adjacent molecules are symmetrically linked to each other to form a dimer with intermolecular Sn···Cl distances of 0.3591(2) nm and the tin atom is five-coordinated in a distorted trigonal bipyramid configuration.
