The structure described by CsNpMoO7 crystallizes in the orthorhombic Pnna space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(2) atoms. Np(1) is bonded to one O(4), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted NpO7 pentagonal bipyramids that share corners with four equivalent Mo(1)O4 tetrahedra. Mo(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form MoO4 tetrahedra that share corners with four equivalent Np(1)O7 pentagonal bipyramids. There are four inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one Np(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Np(1) atom. In the third O site, O(2) is bonded in a 1-coordinate geometry to two equivalent Cs(1), one Np(1), and one Mo(1) atom. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cs(1), one Np(1), and one Mo(1) atom. is represented by the CIF file [CIF]
