Abstract

Abstract The X-ray crystal structures of N,N′-bis(2-hydroxybenzyl)-N,N′-bis(2-methyl-pyridyl)ethylenediamine (H2BBPEN) and the complex [Ru(BBPEN)][PF6]·H2O have been determined. In this complex the two phenolate oxygens, the two aliphatic nitrogens and the pyridine rings lie in cis positions. Two reversible processes at E 1 2 + 0.854 V (RuIV/RuIII) and −0.056 V (RuIII/RuII) versus Fc+/Fc, consistent with one-electron transfer, were detected by cyclic voltammetry. The EPR measurements for the RuIII complex in solid state at room temperature have shown three g-tensor values: gx = 2.4503, gy = 2.2077 and gz = 1.19131, which are in agreement with the distortion of the structure for the complex determined by X-ray diffraction.
