'''草酸铍'''是一种[[无机化合物]]，化学式为{{chem|Be|C|2|O|4}}，是[[铍]]的[[草酸盐]]。<ref>{{cite book |last1=Novoselova |first1=Aleksandra Vasilʹevna |last2=Bat︠s︡anova |first2=Li︠u︡dmila Rafailovna |title=Analytical Chemistry of Beryllium |date=1969 |publisher=Ann Arbor-Humphrey Science Publishers |page=25 |url=https://www.google.ru/books/edition/Analytical_Chemistry_of_Beryllium/2mBNAAAAMAAJ?hl=en&gbpv=1&bsq=beryllium+oxalate&dq=beryllium+oxalate&printsec=frontcover |access-date=15 June 2021 |language=en}}</ref>它是无色晶体，可溶于水，可以形成水合物晶体。它经热分解<ref>{{cite book |last1=Walsh |first1=Kenneth A. |title=Beryllium Chemistry and Processing |date=2009-01-01 |publisher=[[ASM International]] |isbn=978-0-87170-721-5 |page=125 |url=https://www.google.ru/books/edition/Beryllium_Chemistry_and_Processing/3-GbhmSfyeYC?hl=en&gbpv=1&dq=beryllium+oxalate&pg=PA125&printsec=frontcover |access-date=15 June 2021 |language=en}}</ref>可以用来制备高纯度的[[氧化铍]]。<ref>{{cite journal |last1=Dollimore |first1=David |last2=Konieczay |first2=Julie L. |title=The thermal decomposition of beryllium oxalate and related materials |url=https://www.sciencedirect.com/science/article/abs/pii/S0040603198003402 |journal=Thermochimica Acta |access-date=15 June 2021 |pages=155–163 |language=en |doi=10.1016/S0040-6031(98)00340-2 |date=1998-09-07 |volume=318 |issue=1–2 |archive-date=2022-04-01 |archive-url=https://web.archive.org/web/20220401103146/https://www.sciencedirect.com/science/article/abs/pii/S0040603198003402 }}</ref>

==制备==
草酸铍可由[[草酸]]和[[氢氧化铍]]反应得到：<ref>{{cite book |last1=Moore |first1=Raymond E. |title=Purification of Beryllium Compounds: A Literature Survey |date=1960 |publisher=[[Oak Ridge National Laboratory]] |page=6 |url=https://www.google.ru/books/edition/Purification_of_Beryllium_Compounds/kR34mCmtPw0C?hl=en&gbpv=1&bsq=beryllium+oxalate&dq=beryllium+oxalate&printsec=frontcover |access-date=15 June 2021 |language=en}}</ref>

::<math>\mathsf{Be(OH)_2 + H_2C_2O_4 \ \xrightarrow{}\ BeC_2O_4 + 2H_2O }</math>

==性质==
草酸铍的水合物加热失水：
::<math>\mathsf{BeC_2O_4\cdot 3H_2O \ \xrightarrow[-2H_2O]{100^oC}\ BeC_2O_4\cdot H_2O  \ \xrightarrow[-H_2O]{220^oC}\ BeC_2O_4}</math>

需要指出的是，三水合物在50 °C便可缓慢失水，生成一水合物。<ref>Hamner, R. L.; Harris, L. A. Calcination in air of beryllium oxalate trihydrate to beryllium oxide.
