报道了一种合成含三种不同聚吡啶配体的三(双齿)Ru(II)配合物的一般方法，该方法基于配体与齐聚物[Ru(CO)(2)Cl2](N)的顺序加成。用原子吸收光谱和核磁共振波谱对三元杂感配合物进行了表征。测定了配合物[Ru(Me(2)bpy)(Phen)(Bpa)](PF6)(2)的晶体结构。C6H14[C40H43F12N7P2Ru，M=1062.8；Me(2)bpy=4，4‘-二甲基-2，2’-联吡啶，phen=1，10-菲咯啉，bpa=双(2-吡啶)胺：三斜晶系，空间群，a=14.57(3)Angstrom，b=13.50(3)Angstrom，c=12.73(3)Angstrom，α=68.6(2)度，β=63.5(1)度，Gamma=79.8(2)度，V=2082 Angstrom(3)，Z=2。
A general synthetic methodology is reported for tris(bidentate)ruthenium(II) complexes containing three different polypyridyl ligands, based on the sequential addition of the ligands to the oligomer [Ru(CO)(2)Cl-2](n). The tris(heteroleptic) complexes were characterized by FAB mass spectrometry and NMR spectroscopy. An X-ray crystal structure determination was made for the complex, [Ru(Me(2)bpy)(phen)(bpa)](PF6)(2) . C6H14 [C40H43F12N7P2Ru, M = 1062.8; Me(2)bpy = 4,4'-dimethyl-2,2'-bipyridine, phen = 1,10-phenanthroline, bpa = bis(2-pyridyl)amine]: triclinic, space group , a = 14.57(3) Angstrom, b = 13.50(3) Angstrom, c = 12.73(3) Angstrom, alpha = 68.6(2)degrees, beta = 63.5(1)degrees, gamma = 79.8(2)degrees, V = 2082 Angstrom(3), Z = 2. Aspects of the electrochemistry, spectroscopy, and photophysics of the tris(heteroleptic) species are discussed.
