Preparation and characterisation of some new dithiocarbazate schiff base complexes of titanium(IV), tin(IV) and lead(IV)

678-682The dibasic tridentate schiff bases H2SMVD and H2SMND, prepared by the condensation of S-methyldithio-carbazate with 2-hydroxy-3-methpxybenzaldehyd  and 2-hydoxy-l-naphthaldehyde respectively, form neutral penta-coordinated complexes of the type [X2M(schiff base)], (X = Cl, OPri, OBun, Me, Et or Ph) with titanium(IV), tin(IV) and lead(IV) organometallics. The triphenyltin(IV) and triphenyllead(IV) complexes also show evidences for pentacoordination. The complexes are characterised on the basis of IR, 1H NMR and electronic spectral data
