==合成与反应==
草酸锂可由[[草酸]]和[[氢氧化锂]]反应制得：
:: <math>\mathsf{ 2LiOH + H_2C_2O_4 \ \xrightarrow\ Li_2C_2O_4 + 2H_2O }</math>

它和[[草酸铀酰]]按等化学计量比在溶液中煮沸后冷却，可以得到黄色的Li<sub>2</sub>UO<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>2</sub>·5H<sub>2</sub>O晶体。<ref>{{cite journal|journal=Thermochimica Acta|volume=293|issue=1-2|language=en|date=1997-06|pages=163–166|doi=10.1016/S0040-6031(97)00015-4|url=https://linkinghub.elsevier.com/retrieve/pii/S0040603197000154|title=X-ray, thermal and infrared spectroscopic studies on lithium and sodium oxalate hydrates|accessdate=2021-06-16|author=N.D.
