摘　　要：合成并表征了2个基于2⁃取代⁃4,6⁃二吡啶基⁃1,3,5⁃三嗪的双核钌配合物,[Ru2(OBPT)(bpy)4](PF6)3·3H2O·0.5CH3CH2OH(1)和[Ru2(HABPT)(bpy)4](PF6)4·0.5H2O(2),其中bpy=2,2'⁃联吡啶,HOBPT=2⁃羟基⁃4,6⁃(2⁃吡啶基)⁃1,3,5⁃三嗪,HABPT=2⁃氨基⁃4,6⁃(2⁃吡啶基)⁃1,3,5⁃三嗪。分析了2个配合物的单晶结构,其中,1是单斜晶系C2/c空间群,属于外消旋⁃(ΔΔ)型;2属于正交晶系Pca21空间群,属于内消旋⁃(ΔΛ)型。单晶结构表明1中的配体HOBPT是脱质子的,而2中的HABPT没有脱质子。2个配合物的电化学和光谱性质呈现明显的不同,所有数据均表明配合物中2个金属中心间存在电子耦合。Two new dinuclear Ru(Ⅱ) complexes of 2⁃substituted 4,6⁃di(2⁃pyridyl)⁃1,3,5⁃triazine,[Ru2(OBPT)(bpy)4](PF6)3·3H2O·0.5CH3CH2OH(1)and[Ru2(HABPT)(bpy)4](PF6)4·0.5H2O(2),where bpy=2,2'⁃bipyridine,HOBPT=4,6⁃bi(2⁃pyridyl)⁃1,3,5⁃triazin⁃2⁃ol,HABPT=2⁃amino⁃4,6⁃bi(2⁃pyridyl)⁃1,3,5⁃triazine,were synthesized and character⁃ized.The X⁃ray crystal structures of the complexes have been determined,which show that 1 crystallizes in the monoclinic C2/c space group and in the rac⁃(ΔΔ)stereoisomeric form,while 2 in the orthorhombic Pca21 space group and in the meso⁃(ΔΛ)stereoisomeric form.Single⁃crystal structures indicate that the bridging ligand HOBPT in 1 is deprotonated while the ligand HABPT in 2 is not.The electrochemical and spectral properties of two com⁃plexes are significantly different.All data indicate the presence of electronic coupling between the individual metal centers bridged by the ligands in the complexes.CCDC:2026074,1;2026075,2.
