Ten new organotin complexes were synthesized by the reactions of di-and tribenzyltin chloride with corresponding sodium salts of salicylaldehyde thiosemicarbazone,o-vanillin thiosemicarbazone,2,4-dihydroxybenzaldehyde thiosemicarbazone,2,4-dihydroxyacetophenone thiosemicarbazone and o-hydroxyacetophenon thiosemicarbazone.

Six novel heterocyclic organotin(Ⅳ) complexes were synthesized by the reaction of di-(or tri-)benzyltin chloride with tridentate Schiff base ligands which were prepared by the condensation between diamino thiourea and aromatic aldehyde(or aromatic ketone).

The (PhCH2)3SnS2CN (C4H8O) was synthesized by the reaction of tribenzyltin chloride with morpholinyldithiocarbamate, its crystal structure was determined by X-ray single crystal diffraction.

Ten tribenzyltin dithiocarbamates (PhCH2)3SnS2CR (R:(CH2)5N—, (CH3)2N—, (C2H5)2N—, (nC4H9)2N—, (HOCH2CH2)2N—, (C6H5)(COCH3)N—, (C6H5)CH3N—, (C6H5)2N—, C4H4N—, (CH2)2(CO)2N—) were synthesized by reacting tribenzyltin chloride with potassium salts of dithiocarbamic acid.

Triphenylphosphine oxide)dibenzyltin dichloride was synthesized by the reaction of dibenzyltin dichloride with triplhenylphosphine oxide and characterized by elemental analysis.

The reaction of benzylchloride with tin suspended in boiling xylene in the presence of catalytic water directly affords dibenzyltin dichloride(1) in the yield of 90%,and compound (1) reacts with triphenyl phosphine oxide to give the corresponding complexe(2) in the yield of 95%.
