Zr (IV) COMPLEXES OF SOME NITROGEN-OXYGEN DONOR LIGANDS (SEMICARBAZONES & SALICYLALDAZINE)
Keywords:
ligands, zirconium, semicarbazone, characterizationAbstract
Complexes containing mixed ligands of zirconium (IV) have been synthesized by the reaction of zirconium (IV) nitrate (Zr(NO3)4, 5H2O) with salicylaldazine (SAH2) and semicarbazone ligands benzaldehyde semicarbazone (BSCH), 4-methoxybenzaldehyde semicarbzone (MBSCH), 2-chlorobenzaldehyde semicrbazone (CISCH) and cinnamaldehyde semicarbazone (CinSCH) forming complexes of the type [Zr2(SAH)2(SCH)2](NO3)8 and [Zr2(SA)2 (SC)2](NO3)2 in neutral and basic medium respectively. The ligands and their complexes are characterized physico-chemically.Downloads
