Abstract

A series of trans-(FcC_2n)Ru₂(Y-DMBA) ₄(C_2mFc) with n, m = 1 and 2 and Y-DMBA as N,N′-dimethylbenzamidinate or N,N′-dimethyl-(3-methoxy)benzamidinate have been synthesized and characterized. The intramolecular Fc⋯Fc distances, established through single-crystal X-ray diffraction studies, range from 11.6 to 16.6 Å. Results from both voltammetric and spectroelectrochemical studies indicate that the (-C_2n)Ru ₂(Y-DMBA)₄(C_2m-) fragments are among the most efficient mediators of intramolecular hole transfer. Density-functional calculations offer both the insight on the ground-state electronic properties and unambiguous assignment for the observed electronic absorptions.
