The material structure described by CsNpMoO6 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 9-coordinate geometry to one O(1), two equivalent O(3), three equivalent O(2), and three equivalent O(4) atoms. Np(1) is bonded to one O(1), one O(2), one O(3), two equivalent O(5), and two equivalent O(6) atoms to form distorted NpO7 pentagonal bipyramids that share corners with two equivalent Np(1)O7 pentagonal bipyramids, corners with two equivalent Mo(1)O5 trigonal bipyramids,  an edgeedge with one Np(1)O7 pentagonal bipyramid, and edges with two equivalent Mo(1)O5 trigonal bipyramids. Mo(1) is bonded to one O(4), one O(5), one O(6), and two equivalent O(1) atoms to form distorted MoO5 trigonal bipyramids that share corners with two equivalent Np(1)O7 pentagonal bipyramids, edges with two equivalent Np(1)O7 pentagonal bipyramids, and  an edgeedge with one Mo(1)O5 trigonal bipyramid. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Np(1) and one Mo(1) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one Cs(1), one Np(1), and two equivalent Mo(1) atoms. In the third O site, O(2) is bonded in a single-bond geometry to three equivalent Cs(1) and one Np(1) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Np(1) atom. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one Mo(1) atom. In the sixth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Np(1) and one Mo(1) atom. is represented by the CIF file [CIF]
