Lithium oxalate is anorganic compound with the chemical formulaLi2C2O4. It is a salt oflithium metal andoxalic acid.[3][4] It consists of lithiumcationsLi+ andoxalateanionsC2O2−4. Lithium oxalate is soluble in water and converts tolithium oxide when heated.[5]
One of the methods of synthesis is the reaction of direct neutralization ofoxalic acid withlithium hydroxide:
The compound crystallizes in themonoclinic system,cell parametersa = 3.400Å,b = 5.156 Å,c = 9.055 Å,β = 95.60°,Z = 4.[3]
Lithium oxalate decomposes when heated at 410–500 °C (770–932 °F; 683–773 K):
Inpyrotechnics, the compound is used tocolor the flame red.[6]
