PON1 is quartz (alpha)-derived structured and crystallizes in the monoclinic Cc space group. There are three inequivalent P sites. In the first P site, P(1) is bonded to one N(1), one N(2), one N(3), and one O(1) atom to form PN3O tetrahedra that share corners with two equivalent P(2)N2O2 tetrahedra and corners with two equivalent P(3)NO3 tetrahedra. In the second P site, P(2) is bonded to one N(1), one N(3), one O(2), and one O(3) atom to form PN2O2 tetrahedra that share corners with two equivalent P(1)N3O tetrahedra and corners with two equivalent P(3)NO3 tetrahedra. In the third P site, P(3) is bonded to one N(2), one O(1), one O(2), and one O(3) atom to form PNO3 tetrahedra that share corners with two equivalent P(2)N2O2 tetrahedra and corners with two equivalent P(1)N3O tetrahedra. There are three inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the second N site, N(2) is bonded in a bent 150 degrees geometry to one P(1) and one P(3) atom. In the third N site, N(3) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(3) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one P(2) and one P(3) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one P(2) and one P(3) atom.
