Title: Materials Data on PH9(NO2)2 by Materials Project

Abstract

(NH4)2HPO4 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of eight ammonium molecules and two HPO4 ribbons oriented in the (1, 0, 0) direction. In each HPO4 ribbon, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.54–1.60 Å. H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.63 Å) H–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one P5+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one H1+ atom.
