dc.description.abstract This thesis originates from our interest to study the redox reaction of NO assisted with transition metal complexes. Initial aim of the thesis was to synthesize stable metal–nitrosyl complexes and to study the redox reactivity of the coordinated nitrosyl. Since most of the roles played by NO in biological systems are attributed to the formation of nitrosyl complexes of the metallo-proteins, this work would have been helpful to understand the basic chemistry involved in biological reactions. To achieve those, the reactivity of Cu(II) complexes of N-donor ligands have been studied and described in second and third chapters of the thesis. In both the cases, initial attack of NO resulted in the reduction of Cu(II) centre to Cu(I) and the Cu(I) intermediate complex thus formed further reacts with excess NO to afford N2O. In chapter 2, the N2O moiety is found to bind with metal centre to give a stable nitrous oxide complex. DFT calculation suggests that N2O binds to copper centre through nitrogen atom. It loses N2O easily in solution indicating a weak binding of N2O to the metal ion. en_US
