Beryllium oxalate is an inorganic compound, a salt of beryllium metal and oxalic acid with the chemical formula C
₂BeO
₄.^[3] It forms colorless crystals, dissolves in water, and also forms crystalline hydrates. The compound is used to prepare ultra-pure beryllium oxide^[4] by thermal decomposition.^[5]

Synthesis

{\mathsf {Be(OH)_{2}+H_{2}C_{2}O_{4}\ {\xrightarrow {}}\ BeC_{2}O_{4}+2H_{2}O}}

Crystalline hydrates lose water when heated:

{\mathsf {BeC_{2}O_{4}\cdot 3H_{2}O\ {\xrightarrow[{-2H_{2}O}]{100^{o}C}}\ BeC_{2}O_{4}\cdot H_{2}O\ {\xrightarrow[{-H_{2}O}]{220^{o}C}}\ BeC_{2}O_{4}}}
