Nitric oxide spectroscopic characterization

In this paper author reported the reactivity of newly synthesized Co(III)-nitrosyls complexes with superoxide radical to follow nitric oxide dioxygenation. Two new Co(III)-nitrosyl complexes bearing N-tetramethylated cyclam (TMC) ligands, [(12-TMC)-Com(NO)]2+ (1) and [(13-TMC)Coin(NO)]2+ (2), were synthesized via [(TMC)Con(CH3CN)]2+ + NO(g) reactions. Spectroscopic and structural characterization showed that these compounds bind the nitrosyl moiety in a bent end-on fashion. Complexes 1 and 2 reacted with K02/2.2.2-ciyptand to produce [(12-TMC)Con(N02)]+ (3) and [(13-TMC)Con(N02)]+ (4), respectively these possess 0,0 -chelated nitrito ligands.

Inorganic expl materials have also proven to he amenable to IR spectroscopic analysis. An IR spectrophotometric analysis method for carbon monoxide, carbon dioxide, nitric oxide, nitrous oxide and nitrogen dioxide produced in vacuum stability tests of expls stored together with polymeric materials has been developed (Ref 60). Structural properties, as elucidated by IR absorption, of a variety of new perfluorinated and halofluorinated covalent perchlorates are reported in Ref 42.

The first volume starts with an introductory chapter by myself on Historical Introduction to Nitrosyl Complexes recounts the discovery of nitric oxide and its complexes and serves as a general broad introduction to the two volumes. This is followed by a pair of chapters by Dr. Hanna Lewandowska on the Coordination Chemistry of Nitrosyls and Its Biological Implications and the Spectroscopic Characterization of Nitrosyl Complexes. A comprehensive overview is presented of the biologically relevant coordination chemistry of nitrosyls and its biochemical consequences in the first chapter. Representative classes of metal nitrosyls are introduced along with the structural and bonding aspects that may have consequences...
