Synthesis of heteroleptic terpyridyl complexes of Fe(ii) and Ru(ii): optical and electrochemical studies†‡
Abstract
We report the synthesis and characterization of heteroleptic terpyridyl complexes of d6 transition metal ions with Fe2+ and Ru2+ (1–3). Furthermore, we study the effect of substitution of either an electron donating group (–NH2) or electron withdrawing group (–NO2) at the 4′-position in the ligands by means of UV-vis, cyclic voltammetry, and differential pulse voltammetry measurements. The experimentally observed photophysical characteristics of the transition-metal based terpyridyl complexes are explained and supported by detailed quantum chemical calculations.
