摘要：

In this paper, we describe the enantiospecific synthesis and the complete characterization of the two hexacoordinated ruthenium(II) monocations [Ru(bpy)(2)ppy](+) and [Ru(bpy)(2)quo](+) (bpy = 2,2'-bipyridine, ppy = phenylpyridine-H+, quo = 8-hydroxyquinolate) in their enantiomeric Delta and Delta forms. The corresponding enantiomeric excesses (ee's) are determined by H-1 NMR using pure Delta-Trisphat (tris(tetrachlorobenzenedialato)phosphate(V) anion) as a chiral H-1 NMR shift reagent. A complete H-1 and C-13 NMR study has been carried out on rac-[Ru(bPY)(2)ppy]PF6 and rac-[Ru(bpy)(2)quo]PF6. Additionally, the X-ray molecular structure of rac-[Ru(bpy)(2)quo]PF6 is reported; this latter species crystallizes in the monoclinic C2/c space group (a = 22.079 Angstrom, b = 16.874 Angstrom, c = 17.533 Angstrom, (alpha = 90degrees, beta = 109.08degrees, gamma = 90degrees).
