Coordination chemistry of organic nitric oxide derivatives.

• A variety of organic nitric oxide derivatives can act as ligands. • Nitrosoarenes can display redox activity as ligands. • Azodioxide complexes can display unusual coordination geometry. • The coordination chemistry of nitroso compounds is relevant to toxicology. Organic derivatives of nitric oxide can serve as ligands for transition metals in a variety of fashions. This review surveys recent developments in the coordination chemistry of four main classes of organic NO derivatives: nitrosoalkanes and nitrosoarenes, azodioxides, and nitrosamines. Highlighted work includes evidence that nitrosoarenes can behave as redox-active ("non-innocent") ligands, an expansion in the number of crystallographically characterized azodioxide complexes, and the synthesis of N -bound primary nitrosamines. Relevance to the bioinorganic chemistry of metalloenzymes is noted. [ABSTRACT FROM AUTHOR]
