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.[1]

Properties

Ytterbium(III) oxalate pentahydrate is decomposed by heat to obtain the dihydrate, which is further heated to obtain ytterbium(III) oxide.[2][3] It reacts with acids to obtain H[Yb(C2O4)2].6H2O.[4]
