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 O(1), and one O(3) atom to form corner-sharing PN2O2 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 corner-sharing PN2O2 tetrahedra. In the third P site, P(3) is bonded to one N(2), one N(3), one O(1), and one O(2) atom to form corner-sharing PN2O2 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(2) and one P(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 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(1) and one P(2) atom.
