Preparation and Characterization of Tin(II) and Tin(IV) Complexes with Some Morpholine-N-Thiocarbazones

Abstract

Complexes of Sn(ll) and Sn(IV) with benzaldehyde morpholine-N-thiocarbazone
(Benzmtcz-H), cinnamaldehyde morpholine-N-thiocarbazone
(Cinmtcz-H), Cyclohexanone morpholine-N-thio-carbazone
(Cyclmtcz-H), isatine morpholine-N-thiocarbazone (Istmtcz-H), Salicylaldehyde
morpholine-N-thiocarbazone (Salmtcz-H₂) and o-hydroxyacetophenone
morpholine-N-thiocarbazone (Ohacetpmcz-H₂) of composition
{Sn(lI)(LH)₂Cl₂}; (LH = Benzmtcz-H, Cinmtcz-H, Istmtcz-H,
Cyclmtcz-H), [Sn(II)(LH)₂]; (LH₂= Salmtcz-H₂ or Ohacetpmtcz-H₂),
[Sn(IV)L₂] and [Sn(IV)LI₂] (LH₂ = Salmtcz-H₂ or Ohacetpmtcz-H₂ and
[Sn(IV)L₂I₂]; (LH = Benzmtcz-H, Cinmtcz H or Cyclmtcz H) have been
prepared and characterised by elemental analysis, electrical conductance,
IR and NMR spectral studies.
