The material described by PON1 crystallizes in the orthorhombic I2_12_12_1 space group. P(1) is bonded to two equivalent N(1) and two equivalent O(1) atoms to form corner-sharing PN2O2 tetrahedra. N(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. O(1) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms. is represented by the CIF card [CIF]
