The structure described by Cs2NpO3 crystallizes in the orthorhombic Cmc2_1 space group. Cs(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Np(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing NpO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted water-like geometry to four equivalent Cs(1) and two equivalent Np(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to four equivalent Cs(1) and one Np(1) atom. is represented by the CIF file [CIF]
