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]
