Materials Data on PH11S(NO4)2 by Materials Project
(NH2)2H2(PNH6SO7)2(H2O)2 crystallizes in the monoclinic Pc space group. The structure is one-dimensional and consists of two ammonia molecules; two hydrogen molecules; two water molecules; and two PNH6SO7 ribbons oriented in the (0, 1, 0) direction. In each PNH6SO7 ribbon, P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.51–1.58 Å. N1+ is bonded in a bent 120 degrees geometry to one S2- and one O2- atom. The N–S bond length is 1.77 Å. The N–O bond length is 1.34 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a bent 150 degrees geometry to two O2- atoms. There is one shorter (1.08 Å) and one longer (1.38 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.03 Å. In the fourth H1+ site, H1+ is bonded in a 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 linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.44 Å) H–O bond length. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. S2- is bonded in a distorted trigonal non-coplanar geometry to one N1+ and two O2- atoms. There is one shorter (1.49 Å) and one longer (1.61 Å) S–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one H1+ and one S2- atom. In the second O2- site, O2- is bonded in a water-like geometry to one H1+ and one S2- atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one N1+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to three H1+ atoms.
