Studies on Bidentate E,N (E = S, Se, Te), N,N (Redox Active) and Tridentate N,N,N Ligands: Complexes with Lanthanoids, Tin and Transition Metals

thesis
posted on 07.04.2020, 06:00 by Rajesh Deka
The thesis deals with the coordination chemistry of several diverse classes of ligands with different metals. The key features of the thesis are as follows:
1. A series of novel, low molecularity lanthanoid tellurolate complexes are synthesized using intramolecularly coordinated hybrid ligands, namely 2-{(dimethylamino)methyl}phenyl tellurolate and quinoline-8 tellurolate. DFT calculations suggest that the nature of bonding between Te and Ln is predominantly ionic in nature with slight mixing of covalency.
2. The structural characterization of bis(8-sulfanylquinolinium) hexachloridostannate(IV) is reported and its variable reaction behavior in different solvent is explored.
3. A series of novel Ru and Os complexes of bidentate ligand, N,N ́-bis(2-pyridyl)benzene-1,2-diamine are synthesized and their accessible oxidized and reduced forms are experimentally studied.
4. The synthesis and structural aspects of Pd, Pt, Se and Te complexes of pyrrole based NNN-pincer ligands, namely 2,5-bis[(dimethylamino)methyl] pyrrole, 2,5-bis[(pyrrolidino)methyl] pyrrole and 2,5- bis[(piperidino)methyl] pyrrole are explored.
