Materials Data on PH6NO4 by Materials Project
NH4H2PO4 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional and consists of eight ammonium molecules and one H2PO4 framework. In the H2PO4 framework, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.53 Å) and two longer (1.59 Å) P–O bond length. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.43 Å) H–O bond length. There are two 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 bent 120 degrees geometry to one P5+ and one H1+ atom.
