Triphenyltin(IV) complexes of some monobasic bidentate Schiff bases

Seven N-substituted salicylideneiminatotriphenyltin(Iv) chelated complexes of general formula Ph3SnLdagger [HLdagger = o-HOC6H4CH=NC6H4R (R = Cl, Me, OMe, COMe) and o-HOC6H3(OMe)CH=NC6H4Cl] have been synthesized by the reacti on of triphenyltin(IV) chloride and N-arylsalicylideneimines in benzene in presence of triethylamine as Lewis base. The complexes are characterized by Infrared, NMR(H-1 and Sn-119) spectroscopy in addition to elemental analys es. Molecular weight determination in chloroform show them to be monomeric and five coordinated trigonal bipyramidal geometry is proposed for the orga notin(IV) complexes.
