Abstract: 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 characterized. 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 complexes are significantly different. All data indicate the presence of electronic coupling between the individual metal centers bridged by the ligands in the complexes. |
