Lithium oxalate is an inorganic compound, a salt of lithium metal and oxalic acid with the chemical formula C
2Li
2O
4.[3][4] Lithium oxalate is highly insoluble in water and converts to the oxide when heated.[5]
Synthesis[]
One of the methods of synthesis is the reaction of direct neutralization of oxalic acid with lithium hydroxide:
Properties[]
The compound crystallizes in the monoclinic system, cell parameters a = 3.400, b = 5.156, c = 9.055 Å, β = 95.60°, Z = 4.[3]
Lithium oxalate decomposes when heated:
Applications[]
In pyrotechnics, the compound is used to color the flame red.[6]
