'''草酸亚锡'''是一种[[化合物]]，化学式为SnC<sub>2</sub>O<sub>4</sub>。

==制备==
草酸亚锡可由[[草酸]]和[[氧化亚锡]]反应制得：
:<math>\mathsf{ SnO + H_2C_2O_4 \ \xrightarrow{}\ SnC_2O_4\downarrow + H_2O }</math>

它也可由[[氯化亚锡]]和[[草酸]]反应得到。<ref>{{cite journal |last1=Nagirnyak |first1=Svitlana V. |last2=Lutz |first2=Victoriya A. |last3=Dontsova |first3=Tatiana A. |last4=Astrelin |first4=Igor M. |title=Synthesis and Characterization of Tin(IV) Oxide Obtained by Chemical Vapor Deposition Method |journal=[[Nanoscale Research Letters]] |date=26 July 2016 |volume=11 |issue=1 |pages=343 |doi=10.1186/s11671-016-1547-x |url=https://nanoscalereslett.springeropen.com/articles/10.1186/s11671-016-1547-x |access-date=5 August 2021 |issn=1556-276X |archive-date=2022-06-17 |archive-url=https://web.archive.org/web/20220617133933/http://nanoscalereslett.springeropen.com/articles/10.1186/s11671-016-1547-x }}</ref>
