SYNTHESIS, CRYSTAL-STRUCTURE, ELECTROCHEMICAL AND SPECTROSCOPIC PROPERTIES OF [RU(BBPEN)][PF6]CENTER-DOT-H2O - CRYSTAL-STRUCTURE OF THE H(2)BBPEN YBENZYL)-N,N'-BIS(2-METHYLPYRIDYL)ETHYLENEDIAMINE]

The X-ray crystal structures of ybenzyl)-N,N'-bis(2-methyl-pyridyl)eth ylenediamine (H(2)BBPEN) and the complex [Ru(BBPEN)][PF6]. H2O have be en determined. In this complex the two phenolate oxygens, the two alip hatic nitrogens and the pyridine rings lie in cis positions. Two rever sible processes at E(1/2) + 0.854 V (Ru-IV/Ru-III) and -0.056 V (Ru-II I/Ru-II) versus Fc(+)/Fc, consistent with one-electron transfer, were detected by cyclic voltammetry. The EPR measurements for the Ru-III co mplex in solid state at room temperature have shown three g-tensor val ues: g(x) = 2.4503, g(y) = 2.2077 and g(z) = 1.19131, which are in agr eement with the distortion of the structure for the complex determined by X-ray diffraction.
