    Ruthenium complexes with non-innocent quinonoid, quinoline-5,8-dione and iminoquinone ligands : synthesis, structure, redox properties and electron distribution
    (2012) Das, Hari Sankar; Sarkar, Biprajit (Prof. Dr.)
    Redox active quinonoid ligands and their metal complexes are gaining increasing attention because of their wide importance in inorganic, organic, physical and even in bio-chemistry. In this doctoral thesis structural and electronic properties of mono- and dinuclear ruthenium complexes of non-innocent quinonoid bridging ligands have been investigated. Additionally, the thesis covers the straightforward, one-pot and green synthesis of symmetrically and rare asymmetrically substituted biologically relevant p-quinone ligands with different steric and electronic properties. The N-substituents in the ligands are used to tune the structural and electronic properties of their metal complexes.The properties of symmetric and asymmetric non-innocent quinoid ligand systems such as redox, electron transfer, structures, bonding and delocalization of the π-systems have been investigated in their mono- and dinuclear metal complexes.
