Abstract
(NH4)2HPO4 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four ammonium molecules and two NH4HPO4 ribbons oriented in the (1, 0, 0) direction. In each NH4HPO4 ribbon, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.54–1.61 Å. N3- is bonded in a tetrahedral geometry to four H1+ atoms. There are a spread of N–H bond distances ranging from 1.03–1.06 Å. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- and one O2- atom. The H–O bond length is 1.71 Å. In the fourth H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.58 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are four inequivalent O2- sites. In the first O2-more »
