Our research interest is focused on transition and inner-transition metal based co-ordination chemistry which includes synthesis of metal-ligand complexes, characterization by single crystal X-ray crystallography and probing these complexes by various spectroscopic methods (SQUID, VSM, μ-SQUID, EPR, XMCD, and cyclic voltammetry etc. ) to understand the electronic and magnetic properties systematically and develop magneto-structural correlation to fine tune the electronic structures in order to use these molecular nanomagnets for potential technological applications such as information storage, molecular Qubits (for Quantum computing) and Molecular Coolants (for magnetic refrigeration). Coordinately unsaturated organometallic transition metal complexes will be synthesized and their catalytic applications (to activate small molecules such as carbon dioxide, oxygen, nitrogen etc. ) will be investigated in details using various spectroscopic methods. 1) Molecular Nanomagnets 2) Small molecule activation
