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

摘要

Two dibenzyltin(IV)complexes with thiobenzoate ligand,(PhCH2)2Sn(SOCPh)2(1)and(PhCH2)2Sn(Cl)SOCPh(2),have been synthesized by the reaction of dibenzyltin(IV)dichloride with thiobenzoic acid in the presence of organic base Et3N 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.
