The structure described by Np2SO10 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Np sites. In the first Np site, Np(1) is bonded in a 7-coordinate geometry to one O(10), one O(2), one O(3), one O(5), one O(7), and two equivalent O(8) atoms. In the second Np site, Np(2) is bonded in a 7-coordinate geometry to one O(1), one O(10), one O(4), one O(6), one O(7), and two equivalent O(9) atoms. S(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are ten inequivalent O sites. In the first O site, O(6) is bonded in a single-bond geometry to one Np(2) atom. In the second O site, O(7) is bonded in a distorted single-bond geometry to one Np(1) and one Np(2) atom. In the third O site, O(8) is bonded in a distorted bent 150 degrees geometry to two equivalent Np(1) atoms. In the fourth O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Np(2) and one S(1) atom. In the fifth O site, O(9) is bonded in a distorted single-bond geometry to two equivalent Np(2) atoms. In the sixth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Np(1) and one S(1) atom. In the seventh O site, O(10) is bonded in a distorted single-bond geometry to one Np(1) and one Np(2) atom. In the eighth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Np(1) and one S(1) atom. In the ninth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Np(2) and one S(1) atom.
