✦ Synopsis

A nitrosyliron(II)complex with EDTA was produced by reaction of the Fe(H)-EDTA complex and nitrous acid in citric acid-phosphate buffer solution The expcrimcntal results pointed out that nitrous acid is reduced to nitrous oxide by Fe(II)-EDTA complex followed by the form&m reaction of nitrosyliron(IIlEDTA complex. The composition of this compkx was determined to be Fe(II) (NO), EDTA by both electrochemical and spectrosco& methods.

A mechanism of the oxidation of Fe(II) (NO),EDTA was proposed in which nitrous oxide breaks away from the iron ion. The photoeffect on this reaction is discussed.
