The structure described by Ni(PO3)3 crystallizes in the triclinic P-1 space group. Ni(1) is bonded to one O(1), one O(2), one O(4), one O(9), and two equivalent O(3) atoms to form NiO6 octahedra that share  a cornercorner with one P(3)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and  an edgeedge with one Ni(1)O6 octahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(5), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Ni(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 45-49°. In the second P site, P(2) is bonded to one O(3), one O(5), one O(6), and one O(9) atom to form PO4 tetrahedra that share corners with three equivalent Ni(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(3)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-58°. In the third P site, P(3) is bonded to one O(4), one O(6), one O(7), and one O(8) atom to form PO4 tetrahedra that share  a cornercorner with one Ni(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Ni(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Ni(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Ni(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Ni(1) and one P(3) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one P(2) and one P(3) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one P(1) and one P(3) atom. In the eighth O site, O(8) is bonded in a single-bond geometry to one P(3) atom.
