Studies on the Transition Metal Complexes of Acids and Imides with Amine Bases

Abstract

This thesis is presented on the interaction of metal ions with stoichiometric amounts of organic ligands containing O and N donors of which metal complexes have been widely used in biological and catalytical point of view. The thesis is divided into ten chapters. 1. First one is an introductory chapter. The chapter is designed to provide sufficient background and usefulness of the present study. 2. The second chapter describes the experimental techniques which include the physical measurement and analytical techniques. 3. Third chapter has been devoted to the preparation and characterization of mixed ligands complexes of Zr (VI) ions with oxalic acid and hetero cyclic amines. The general formula of the complexes are as follows; [Zr (IV) (oxa)2 L2]. Where oxa = oxalic acid L = Q, 2-Apy, 8-HQ, a-Pie, 2,2'-Bipy. The complexes were prepared in the solid form and characterized by elemental analysis, conductivity, magnetic measurements, infrared, and electronic spectroscopic studies. The infrared spectra of the complexes confirmed the co-ordination of metal ion with ligands. The presence of water molecule inside the co­ordination sphere was also confirmed by infrared spectra. Electronic spectra and magnetic measurement confirmed that the Zr (IV) complexes were of octahedral structure……………………..
