By the reaction of chiral Mn(III) Schiff-base complexes with the dicyanoruthenate building block, [Ru(salen)(CN)2](-) (salen(2-) = N,N'-ethylenebis(salicylideneimine) dianion), two couples of enantiomerically pure chiral cyano-bridged heterobimetallic one-dimensional (1D) chain complexes, [Mn((R,R)-salcy)Ru(salen)(CN)2]n (1-(RR)) and [Mn((S,S)-salcy)Ru(salen)(CN)2]n (1-(SS)) (Salcy = N,N'-(1,2-...

Inert and optically active pseudo-octahedral Cr(III)N6 and Ru(II)N6 chromophores have been incorporated by self-assembly into heterobimetallic triple-stranded helicates HHH-[CrLnL3]6+ and HHH-[RuLnL3]5+. The crystal structures of [CrLnL(3)](CF(3)SO(3))(6) (Ln=Nd, Eu, Yb, Lu) and [RuLnL3](CF3SO3)5 (Ln=Eu, Lu) demonstrate that the helical structure can accommodate metal ions of different sizes, w...
