[Co(qn)<SUB>2</SUB>]· 2H<SUB>2</SUB>O (<B>1</B>) (qn=8-quinolinolate ion) and [Co(NO)(qn)<SUB>2</SUB>] (<B>2</B>) reacted with NO in 10 vol% pyridine–DMF or pyridine to give the nitrato complex, [Co(NO<SUB>3</SUB>)(qn)<SUB>2</SUB>L] (L=pyridine or DMF), with liberation of N<SUB>2</SUB>O. [Co(NO)(qn)<SUB>2</SUB>(py)] (py=pyridine) having NO<SUP>−</SUP> group (<B>3</B>) reacted with NO in CH<SUB>2</SUB>Cl<SUB>2</SUB>, the py–DMF, or pyridine to give [Co(qn)<SUB>2</SUB>(NO<SUB>3</SUB>)(py)] with liberation of N<SUB>2</SUB>O. The mass analyses of the residual NO for the reaction of <B>2</B> or <B>3</B> with NO in the pyridine medium and for the reaction of <B>3</B> with NO in CH<SUB>2</SUB>Cl<SUB>2</SUB>, using the nitrogen-15 labelled compounds showed that a perfect nitrogen scramble occurred between the NO gas and the NO group of <B>2</B> or <B>3</B>. In the reaction of <B>2</B> with NO in CH<SUB>2</SUB>Cl<SUB>2</SUB>, ca. 80% of the coordinating NO reacted with NO gas accompanying a rupture of the original Co–NO bond. The present results were compared with those obtained in the cases that 2-methyl-, 4-methyl-, 5-chloro-, and 5-nitro-8-quinolinolate ions were used as ligands. The electronic effects caused by the substituent of the quinoline ring and by the solvents on the reactions were discussed.
