Electron transfer study on newly synthesized Ti(IV)/Zr(IV) complexes of amide and oxime functionality: A pulse radiolytic and theoretical revelation

Abstract

Complexes of the general formula Cp₂Ti(IV)L, Cp₂Zr(IV)L, Cp₂Ti(IV)L¹ and Cp₂Zr(IV)L¹ have been synthesized with N, N’-bis(2-pyridyl)pyridine-2,6-dicarboxamide(H₂L) and 9, 10-phenanthrenequinone dioxime (H₂L¹). The complexes have been characterized by different spectral techniques and their reduction reactions were carried out with hydrated electron as reducing radical, mechanism has been explored pulse radiolytically. Theoretical calculations have been performed to understand the effect of chelation and electron transfer processes in complexes.
