Preparation and characterisation of tin(II) and tin(IV) complexes with some morpholine-N-thiocarbazones

Complexes of Sn(II) and Sn(IV) with benzaldehyde morpholine-N-thiocarbazone (Benzmtcz-H), cinnamaldehyde morpholine-N-thiocarbazone (Cinmtcz-M, Cyclohexanone morpholine-N-thio-carbazone (Cyclmtcz-H), isatine morpholine-N-thiocarbazone (Istmtcz-H), Salicylaldehyde morpholine-N-thiocarbazone (Salmtcz-H-2) and o-hydroxyacetophenone morpholine-N-thiocarbazone (Ohacetpmcz-H-2) of composition {Sn(II)(LH)(2)Cl-2}; (LH = Benzmtcz-H, Cinmtcz-H, Istmtcz-H, Cyclmtcz-H), [Sn(II)(LH)(2)]; (LH2 = Salmtcz-H-2 or Ohacetpmtcz-H-2), [Sn(IV)L-2] and [Sn(IV)LI2] (LH2 = Salmtcz-H or Ohacetpmtcz-H-2) 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.
