The material described by (NdP2(HO3)2)2H2 crystallizes in the monoclinic P2_1/c space group. The structure consists of four 1333-74-0 atoms inside a NdP2(HO3)2 framework. In the NdP2(HO3)2 framework, Nd(1) is bonded to one O(1), one O(2), one O(4), one O(5), two equivalent O(3), and two equivalent O(6) atoms to form distorted NdO8 hexagonal bipyramids that share corners with two equivalent P(1)HO3 tetrahedra, edges with two equivalent Nd(1)O8 hexagonal bipyramids, and  an edgeedge with one P(1)HO3 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one H(2), one O(1), one O(4), and one O(6) atom to form distorted PHO3 tetrahedra that share corners with two equivalent Nd(1)O8 hexagonal bipyramids and  an edgeedge with one Nd(1)O8 hexagonal bipyramid. In the second P site, P(2) is bonded in a distorted trigonal non-coplanar geometry to one H(1), one O(2), and one O(5) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one P(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one P(1) atom. There are six inequivalent O sites. In the first O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Nd(1) and one O(5) atom. In the second O site, O(4) is bonded in a distorted water-like geometry to one Nd(1) and one P(1) atom. In the third O site, O(5) is bonded in a distorted single-bond geometry to one Nd(1), one P(2), and one O(3) atom. In the fourth O site, O(6) is bonded in a 3-coordinate geometry to two equivalent Nd(1) and one P(1) atom. In the fifth O site, O(1) is bonded in a distorted linear geometry to one Nd(1) and one P(1) atom. In the sixth O site, O(2) is bonded in a distorted single-bond geometry to one Nd(1) and one P(2) atom. is represented by the CIF file [CIF]
