The compound described by P4ON6 crystallizes in the orthorhombic Pnnm space group. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form PN4 tetrahedra that share corners with four equivalent P(2)N3O tetrahedra and  an edgeedge with one P(1)N4 tetrahedra. In the second P site, P(2) is bonded to one N(2), two equivalent N(1), and one O(1) atom to form PN3O tetrahedra that share  a cornercorner with one P(2)N3O tetrahedra and corners with four equivalent P(1)N4 tetrahedra. There are two 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 distorted trigonal planar geometry to one P(2) and two equivalent P(1) atoms. O(1) is bonded in a linear geometry to two equivalent P(2) atoms. is represented by the CIF file [CIF]
