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

Abstract

The 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.
