text: Ytterbium reacts with oxygen to form ytterbium(III) oxide (Yb 2 O 3 ), which crystallizes in 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.
