have been also performed on these complexes and their achiral analogues previously reported in our group, to interpret and complement experimental results. Whereas isomerically pure complexes ([Ru(II)Cl(L2)(bpy)](BF4), 5 and [Ru(II)Cl(L2)(dppe)](BF4), 6) are obtained when starting from the highly symmetric [Ru(III)Cl3(L2)], 2, isomeric mixtures of cis, fac-[Ru(II)Cl(L1)(bpy)](BF4) (3b/3b'), trans,fac-
一套新的Ru-Cl配合物,包含the烯[5,6] bpea配体(L1)或C3对称pin烯[4,5] tpmOMe(L2)三齿配体与二齿(B)2,2'已经制备并彻底表征了具有通式[RuCl(L1或L2)(B)](+)的-联吡啶(bpy)或1,2-二苯基膦基乙烷(dppe)。在固态下,已使用X射线衍射分析技术。在溶液中,已采用循环伏安法(CV)以及1D和2D NMR光谱。对这些配合物及其先前在我们小组中报道的非手性类似物也进行了DFT计算,以解释和补充实验结果。当从高位开始时,会获得异构纯的配合物([Ru(II)Cl(L2)(bpy)](BF4),5和[Ru(II)Cl(L2)(dppe)](BF4),6)。对称[Ru(III)Cl3(L2)],2,
