Ytterbium(III) oxide

Ytterbium(III) oxide is the chemical compound with the formula Yb2O3.

It is one of the more commonly encountered compounds of ytterbium.

It occurs naturally in trace amounts in the mineral gadolinite.

It was first isolated from this in 1878 by Jean Charles Galissard de Marignac.

[2] It reacts with carbon tetrachloride[6] or hot hydrochloric acid to form ytterbium(III) chloride:[7] Like the other trivalent oxides of the heavier lanthanides, ytterbium(III) oxide has the "rare-earth C-type sesquioxide" structure which is related to the fluorite structure with one quarter of the anions removed, leading to ytterbium atoms in two different six coordinate (non-octahedral) environments.
