Abstract

original image

A completely conjugated π system with participation of the Ru centers characterizes the cationic complex 14 +, which was formed from the analogous mononuclear RuII complex by selective C4-C4′ coupling. This is confirmed by crystallographic and NMR spectroscopic findings as well as the fact that strong electronic communication is displayed between RuII and RuIII in 13+.
