Caesium oxalate (standard IUPAC spelling) dicesium oxalate, or cesium oxalate (American spelling) is the oxalate of caesium. Caesium oxalate has the chemicals formula of Cs2C2O4. Not much is known about caesium oxalate has caesium[1]
Preparation
Caesium oxalate can be prepared by passing carbon monoxide and carbon dioxide over caesium carbonate at 380°C:[2]
- Cs2CO3 + CO + CO2 → Cs2C2O4 + CO2
Other alkali carbonates do not undergo transformation to oxalate.[2]
Chemical Reactions
Caesium oxalate can be reduced back into caesium carbonate and carbon dioxide by thermal decomposition.
- Cs2C2O4 → Cs2CO3 + CO
Double salts
Compounds that contain caesium and another element in addition to the oxalate anion are double salts. The oxalate may form a complex with a transition metal that can make a salt with caesiom.
Examples include: a caesium neptunium oxalate.[3]
