Ytterbium(III) oxalate is the oxalate of ytterbium, with the chemical formula Yb2(C2O4)3.

Preparation
Ytterbium(III) oxalate hydrate can be prepared by reacting an aqueous solution of ytterbium(III) chloride and a benzene solution of dimethyl oxalate.

Properties
Ytterbium(III) oxalate pentahydrate is decomposed by heat to obtain the dihydrate, which is further heated to obtain ytterbium(III) oxide. It reacts with acids to obtain H[Yb(C2O4)2].6H2O.
