The structure described by In2P3H3O10 crystallizes in the monoclinic P2_1 space group. There are two inequivalent In sites.

In the second In site, In(2) is bonded to one O(1), one O(10), one O(2), one O(5), one O(6), and one O(9) atom to form InO6 octahedra that share  a cornercorner with one P(1)HO3 tetrahedra, corners with two equivalent P(2)HO3 tetrahedra, corners with two equivalent P(3)HO3 tetrahedra, and  an edgeedge with one In(1)O6 octahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one H(3), one O(1), one O(3), and one O(8) atom to form distorted PHO3 tetrahedra that share  a cornercorner with one In(2)O6 octahedra and corners with two equivalent In(1)O6 octahedra.

The corner-sharing octahedral tilt angles range from 31-54°. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one P(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one P(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one P(1) atom. There are ten inequivalent O sites.
