摘要：

The mononuclear cations of the general formula [(eta(6)-arene)RuCl(dpqMe(2))](+) (dpqMe(2) = 6,7-dimethyl-2,3-di(pyridine-2-yl)quinoxaline; arene = C6H6, 1; C6H5Me, 2; p-(PrC6H4Me)-C-i, 3; C6Me6, 4) as well as the dinuclear dications [(eta(6)-arene)(2)Ru2Cl2(mu-dpqMe(2))](2+) (arene = C6H6, 5; C6H5Me, 6; p-PriC6H4Me, 7; C6Me6, 8) have been synthesised from 6,7-dimethyl-2,3-di(pyridine-2-yl)quinoxaline (dpqMe(2)) and the corresponding chloro complexes [(eta(6) -C6H6)Ru(mu-Cl)Cl](2), [(eta(6) -C6H5Me)Ru(mu-Cl)Cl](2), [(eta(6)-p-(PrC6H4Me)-C-i)Ru(mu-Cl)Cl](2) and [(eta(6) -C6Me6)Ru(mu-Cl)Cl](2), respectively. The X-ray crystal structure analyses of [1][PF6], [3][PF6] and [6][PF6](2) reveal a typical piano-stool geometry around the metal centre; in the dinuclear complexes the two chloro ligands, with respect to each other, are found to be trans oriented.
