Oxalate nitrate

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
An 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
Most oxalate nitrates are formed by crystallisation from water solutions. One issue is the insolubility of metal oxalates.

Properties
On heating, oxalate nitrates lose NO2, NO, CO, and CO2 and form metal carbonates or oxides.
