The material described by NaNp(HO2)2 crystallizes in the orthorhombic P2_12_12_1 space group. Na(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(1) atoms. Np(1) is bonded to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form a mixture of edge and corner-sharing NpO7 pentagonal bipyramids. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(4) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Na(1) and one Np(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Na(1), two equivalent Np(1), and one H(2) atom. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Na(1) and two equivalent Np(1) atoms. In the fourth O site, O(4) is bonded in a single-bond geometry to one Na(1), two equivalent Np(1), and one H(1) atom. is represented by the CIF card [CIF]
