Research Interests
Transition metal complexes constitute an active area f research in the contemporary Inorganic Chemistry. They play a very important role in the field of bioinorganic chemistry and preparation of organic materials favoring an intimate mixing of the elements which can enable reactions at lower temperature rather than the traditional route or the preparation of purer inaccessible solid state phases. The molecular complexes containing two or more same or different metal ions are of interest in homogeneous and heterogeneous catalysis. The heterobimetallic complexes offer an unusual opportunity to study the cooperative interactions between metal ions and have potential to mediate certain chemical reactions of industrial importance either ore efficiently than or in different manner to isolated metal centres.
