The structure described by FePH4(NO2)2 crystallizes in the orthorhombic Pccn space group. Fe(1) is bonded to two equivalent N(1), two equivalent O(1), and two equivalent O(2) atoms to form FeN2O4 octahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Fe(1)N2O4 octahedra. The corner-sharing octahedral tilt angles range from 31-43°. N(1) is bonded in a distorted water-like geometry to one Fe(1), one H(1), and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Fe(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Fe(1) and one P(1) atom. is represented by the CIF file [CIF]
