The structure described by Pu2O3 crystallizes in the trigonal P-3m1 space group. Pu(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to six equivalent Pu(1) atoms to form OPu6 octahedra that share corners with twelve equivalent O(2)Pu4 tetrahedra, edges with six equivalent O(1)Pu6 octahedra, and edges with six equivalent O(2)Pu4 tetrahedra. In the second O site, O(2) is bonded to four equivalent Pu(1) atoms to form OPu4 tetrahedra that share corners with six equivalent O(1)Pu6 octahedra, corners with six equivalent O(2)Pu4 tetrahedra, edges with three equivalent O(1)Pu6 octahedra, and edges with three equivalent O(2)Pu4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-56°. is represented by the Crystallographic Information File (CIF) [CIF]
