Nitrate nitrite

A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO−2) and nitrate (NO−3) anions. They are mixed-anion compounds, and they are mixed-valence compounds. Some have third anions. Many nitrite nitrate compounds are coordination complexes of cobalt. Such a substance was discovered by Wolcott Gibbs and Frederick Genth in 1857.^{[citation needed]}

Production

Mercury(II) nitrate and potassium nitrate in water solution produce the salt tripotassium tetranitratomercurate(II) nitrate K₃[Hg(NO₂)₄]NO₃.^[1]

Properties

On heating, nitrate nitrites lose NO₂ and NO and yield metal oxides.

Related

Other compounds having an element in two different anion states include the sulfate sulfites, the phosphate phosphites, arsenate arsenites and the selenate selenites.
