The material described by Ni(PO3)4 crystallizes in the monoclinic Cc space group. Ni(1) is bonded to one O(11), one O(12), one O(3), one O(4), one O(6), and one O(7) atom to form NiO6 octahedra that share  a cornercorner with one P(1)O4 tetrahedra,  a cornercorner with one P(2)O4 tetrahedra, corners with two equivalent P(3)O4 tetrahedra, and corners with two equivalent P(4)O4 tetrahedra. There are four inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(5), one O(8), and one O(9) atom to form PO4 tetrahedra that share  a cornercorner with one Ni(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra.
