An oxalate nitrate is a chemical compound or salt that contains oxalate and nitrate anions (NO3- and C2O42-). These are mixed anion compounds. Some have third anions. Oxalate acts as a ligand, which normally complexes two metal atoms.
Naming
editAn oxalate nitrate compound may also be called a nitrate oxalate. In chemical formulae, oxalate may be indicated by "ox". As a ligand oxalate is termed "oxalato", and nitrate, "nitrato".
Production
editMost oxalate nitrates are formed by crystallisation from water solutions. One issue is the insolubility of metal oxalates.
Properties
editOn heating, oxalate nitrates lose NO2, NO, CO, and CO2 and form metal carbonates or oxides.
Related
editRelated to these are the oxalate phosphates and oxalate perchlorates.
