Caesium oxalate has the chemicals formula of Cs2C2O4. Not much is known about caesium oxalate has caesium[1] PreparationCaesium 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 ReactionsCaesium oxalate can be reduced back into caesium carbonate and carbon dioxide by thermal decomposition. Cs2C2O4 → Cs2CO3 + CO Double saltsCompounds 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] Related
