The crystal structure described by Pu2O3 is Spinel-derived structured and crystallizes in the monoclinic C2/c space group. There are six inequivalent Pu sites. In the first Pu site, Pu(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. In the second Pu site, Pu(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. In the third Pu site, Pu(3) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. In the fourth Pu site, Pu(4) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles range from 58-59°. In the fifth Pu site, Pu(5) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles are 59°. In the sixth Pu site, Pu(6) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms to form a mixture of distorted corner and edge-sharing PuO6 octahedra. The corner-sharing octahedral tilt angles are 59°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Pu(1), one Pu(2), one Pu(3), and one Pu(5) atom to form a mixture of corner and edge-sharing OPu4 tetrahedra. In the second O site, O(2) is bonded to one Pu(1), one Pu(2), one Pu(3), and one Pu(6) atom to form a mixture of corner and edge-sharing OPu4 tetrahedra. In the third O site, O(3) is bonded to one Pu(1), one Pu(2), one Pu(4), and one Pu(5) atom to form a mixture of corner and edge-sharing OPu4 tetrahedra. In the fourth O site, O(4) is bonded to one Pu(1), one Pu(2), one Pu(4), and one Pu(5) atom to form a mixture of corner and edge-sharing OPu4 tetrahedra.
