      More Details Abstract Fulltext PDF

      Equimolar and bimolar reactions of zirconium isopropoxide with bibasic tridentate azomethine (AZH2) having the donor system ONO have been carried out and derivatives of the type Zr(OPr1)2(AZ) and Zr(AZ)2 [Where AZ2− is the anion of the azomethine molecule] have been isolated. The labile nature of the isopropoxy groups in 1∶1 derivatives has been shown by carrying out exchange reactions with equimolar amount of 2-methylpentane-2,4-diol. All the newly synthesized derivatives have been characterized on the basis of elemental analysis, conductance measurements, molecular weight determinations and infrared, ultraviolet, visible and proton magnetic resonance spectral studies.

      More Details Abstract Fulltext PDF

      An interesting series of some sulphur-bonded unusual bicoordinated thallium(I) complexes of the type TIL (where L is the anion of a monobasic bidentate thiosemicarbazone) has been obtained by the equimolar reactions of thallous chloride with the sodium salt of the ligands (thiosemicarbazones) derived from the condensation of heterocyclic aldehydes or ketones with thiosemicarbazide. The complexes have been characterized by elemental analyses, conductance measurements, molecular weight determinations and electronic, IR,1H and13C NMR spectral studies.
