Zusammenfassung
A review. Coordination compds. [Ru(NO)Ln] contg. an electro-active metal and potentially noninnocent ligands NO (and L) can have ground state electronic structures formulated as RuIII(NO+) = RuNO5, RuII(NO+) = RuNO6, RuII(NO$\surd$) = RuNO7 or RuII(NO-) = RuNO8. The neighboring states of the RuNO6 systems can be accessed by spectroelectrochem. methods or through chem. reactions. The co-ligands Ln affect the electronic structures of the quite variable RuNO6 examples, in contrast to the more invariant RuNO7 species. Potential electro-active co-ligands L such as porphyrins or quinones provide addnl. alternatives for the electronic structures. [on SciFinder(R)]
