description: SrC3P3NH10O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.46–2.91 Å. There are three inequivalent C2- sites. In the first C2- site, C2- is bonded to one P5+, one N3-, and two H1+ atoms to form distorted corner-sharing CPH2N tetrahedra. The C–P bond length is 1.85 Å. The C–N bond length is 1.51 Å. Both C–H bond lengths are 1.10 Å. In the second C2- site, C2- is bonded to one P5+, one N3-, and two H1+ atoms to form distorted corner-sharing CPH2N tetrahedra. The C–P bond length is 1.84 Å. The C–N bond length is 1.51 Å. Both C–H bond lengths are 1.10 Å. In the third C2- site, C2- is bonded to one P5+, one N3-, and two H1+ atoms to form distorted corner-sharing CPH2N tetrahedra. The C–P bond length is 1.84 Å. The C–N bond length is 1.51 Å. Both C–H bond lengths are 1.10 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one C2- and three O2- atoms to form distorted PCO3 tetrahedra that share a cornercorner with one NHC3 tetrahedra. There is two shorter (1.52 Å) and one longer (1.60 Å) P–O bond length. In the second P5+ site, P5+ is bonded to one C2- and three O2- atoms to form distorted PCO3 tetrahedra that share a cornercorner with one NHC3 tetrahedra. There are a spread of P–O bond distances ranging from 1.51–1.59 Å. In the third P5+ site, P5+ is bonded to one C2- and three O2- atoms to form PCO3 tetrahedra that share a cornercorner with one NHC3 tetrahedra. There is two shorter (1.51 Å) and one longer (1.60 Å) P–O bond length. N3- is bonded to three C2- and one H1+ atom to form distorted NHC3 tetrahedra that share corners with three PCO3 tetrahedra. The N–H bond length is 1.04 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the eighth 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 ninth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.70 Å) H–O bond length. In the tenth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.52 Å) H–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+, 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. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to one P5+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sr2+, one P5+, and one H1+ atom. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Sr2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Sr2+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to one P5+ and one H1+ atom.
