The material structure described by La2O3 crystallizes in the trigonal P321 space group. La(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted face, corner, and edge-sharing LaO6 pentagonal pyramids. O(1) is bonded in a square co-planar geometry to four equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
