Pu(SeO3)2 crystallizes in the monoclinic P2_1/c space group. Pu(1) is bonded in a 8-coordinate geometry to one O(1), one O(4), one O(5), one O(6), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2), one O(3), and one O(4) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one O(1), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Pu(1) and one Se(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Pu(1) and one Se(1) atom.
