Synthesis and Characterisation of Titanium(IV), Tin(IV), and Lead(IV) Complexes of Schiff Bases Derived from S-Benzyldithiocarbazate

Abstract

The Schiff bases H₂SBVD and H₂SBND, derived, respectively, from S-benzyldithiocarbazate and 2-hydroxy-3-methoxybenzaldehyde or 2-hydroxy-1-naphthaldehyde, react with titanium tetrachloride, titanium tetraalkoxides, dicyclopentadienyltitanium dichloride, organotin chlorides/oxides/hydroxides and di-/triphenyllead chlorides in 1:1 molar proportion to yield neutral penta-coordinated complexes of the type X₂M(Schiff base) and Ph₃M(H-Schiff base) (M - Sn or Pb). The complexes are characterised on the basis of IR, ¹H NMR and electronic spectral studies.
