# Carbonate nitrate

Carbonate nitrates are mixed anion compounds containing both carbonate and nitrate ions.
Hydrotalcite can contain carbonate and nitrate ions between its layers. Magnesium can be substituted by nickel, cobalt or copper.
Oxycarbonitrates containing an alkaline earth metal and cuprate and nitrate and carbonate anions in layers, form a family of superconducting materials.
