'''硒酸金'''是一种[[无机化合物]]，[[化学式]]为Au<sub>2</sub>(SeO<sub>3</sub>)<sub>2</sub>(SeO<sub>4</sub>)，难溶于水。

==制备==
硒酸金由98%的[[硒酸]]和[[金]]加热反应得到<ref name=wjhxcs6>无机化学丛书.第六卷 卤素 铜分族 锌分族. 张青莲 主编. 3.6.6 硒酸盐、亚硒酸盐、硫氰酸盐和硒氰酸盐.

但是，直到一百年后，生成的这种橙黄色物质才被人们确定为Au<sub>2</sub>(SeO<sub>3</sub>)<sub>2</sub>(SeO<sub>4</sub>)，而非Au<sub>2</sub>(SeO<sub>4</sub>)<sub>3</sub>。<ref name="Wickleder Büchner Wickleder el Sheik 2004 pp. 5860–5864">{{cite journal | last=Wickleder | first=Mathias S. | last2=Büchner | first2=Oliver | last3=Wickleder | first3=Claudia | last4=el Sheik | first4=Sherif | last5=Brunklaus | first5=Gunther | last6=Eckert | first6=Hellmut | title=Au2(SeO3)2(SeO4):  Synthesis and Characterization of a New Noncentrosymmetric Selenite−Selenate | journal=Inorganic Chemistry | publisher=American Chemical Society (ACS) | volume=43 | issue=19 | year=2004 | issn=0020-1669 | doi=10.1021/ic049270z | pages=5860–5864}}</ref>

==化学性质==
硒酸金高温分解产生[[金]]、[[二氧化硒]]和[[氧气]]。

和[[盐酸]]反应，得到[[四氯合金(I)酸]]和[[二氧化硒]]，并放出[[氯气]]。<ref name="wjhxcs6" />
