Materials Data on PH2NO2 by Materials Project
NP(OH)2 crystallizes in the orthorhombic Cmme space group. The structure is two-dimensional and consists of one NP(OH)2 sheet oriented in the (0, 0, 1) direction. P5+ is bonded to two equivalent H1+ and two equivalent O2- atoms to form distorted PH2O2 tetrahedra that share corners with four equivalent NO4 tetrahedra. Both P–H bond lengths are 1.43 Å. Both P–O bond lengths are 1.52 Å. N3- is bonded to four equivalent O2- atoms to form distorted NO4 tetrahedra that share corners with four equivalent PH2O2 tetrahedra and edges with two equivalent NO4 tetrahedra. All N–O bond lengths are 2.81 Å. H1+ is bonded in a single-bond geometry to one P5+ atom. O2- is bonded in a single-bond geometry to one P5+ and two equivalent N3- atoms.
