The material structure described by Pu2SiO10 crystallizes in the tetragonal I4_1/amd space group. Pu(1) is bonded to one O(3), two equivalent O(1), and four equivalent O(2) atoms to form distorted PuO7 pentagonal bipyramids that share corners with two equivalent Si(1)O4 tetrahedra, edges with two equivalent Pu(1)O7 pentagonal bipyramids, and  an edgeedge with one Si(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(2) atoms to form SiO4 tetrahedra that share corners with four equivalent Pu(1)O7 pentagonal bipyramids and edges with two equivalent Pu(1)O7 pentagonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Pu(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Pu(1) and one Si(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Pu(1) atom. is represented by the CIF file [CIF]
