Reactions of chloro-bridged dimeric Ru(II) complexes [Ru(η6-arene)Cl2}2] with bridging ligands 1,4-dicyanamidobenzene, N,N′-dicyano 4-4′-diaminobiphenyl, 2,5-dichloro-1,4-dicyanamidobenzene and 2,5-dimethyl-1,4-dicyanamidobenzene (referred hereafter as dcdH2, bpH2, ddcl and dmcd) in dicloromethane at room temperature gave binuclear complexes with the general formulation [Ru(η6-arene)Cl2}2(μ-L)].
的反应氯桥二聚的Ru(II)配合物[茹(η 6 -arene)氯2 } 2 ]与桥连配体的1,4- dicyanamidobenzene,Ñ,Ñ '-dicyano 4-4'-二氨基联苯,2,5-二氯-1,4- dicyanamidobenzene和2,5-二甲基-1,4- dicyanamidobenzene(以下简称dcdH 2,BPH 2在室温下在dicloromethane,DDCL和DMCD),得到双核络合物与一般的制剂[茹( η 6 -arene)氯2 } 2(μ-L)]。然而,随着这些配合物的配体桥接的反应的[Ru(η 6 -arene)(P)氯2 ](η 6 -arene =苯或p -cymene; P = PPH 3, PET 3或MePPr我2)在甲醇,在NH存在4 PF 6,得到阳离子芳烃络合物[茹(η 6 -arene)(P)氯} 2(L)] 2+(L = dcdH
