The title complex, [2-(2-hydroxyphenyl)iminomethyl benzenethiolato(2-)-N, O, S] (2-methoxycarbonylethyl-C, O) tin chloride, CH3OCOCH2CH2SnClL(L=2-SC6H4CHN=C6H4O2), was synthesized by the reaction of 2 methoxycarbonylethyltin trichloride with N (2 hydroxy phenyl)thiosalicylideneimine. This complex reacted with neutral monodentate ligands such as dimethylsulfoxide(DMSO) and hexamethylphosphoramide(HMPA) to form the mixed ligand complexes, CH3OCOCH2CH2SnClLL′(L′=DMSO, HMPA), and also readily underwent transesterification with alcohols to produce the corresponding2alkoxycarbonylethyltin analogues, ROCOCH2CH2SnClL. These complexes were characterized by means of elemental analysis, IRand 1H NMRspectra. The crystal structure for the title complex was determined by X-ray diffraction analysis. The crystal belongs to triclinic system, space group P1with cell parameters α=0.8704(2) nm, b=0.9393(3) nm, c=1.4511(3) nm, α=98.05(3)°, β=103.03(3)°, γ=6.99(3)°, V=1.1299(4) nm3, Z=2, Dc=1.378 g/cm3, F (000)=524. In this compound, the tin atom adopts a distorted octahedral geometry via intramolecular carbonyl oxygen atom and the sulfur, nitrogen and oxygen atoms of the chelating ligand Lto tin coordination.
