Materials Data on Ca3P4H20(NO10)2 by Materials Project
Ca3P4(H3O5)4(NH4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four ammonium molecules and one Ca3P4(H3O5)4 framework. In the Ca3P4(H3O5)4 framework, there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with two equivalent CaO7 pentagonal bipyramids and corners with four PO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.31–2.48 Å. In the second Ca2+ site, Ca2+ is bonded to seven O2- atoms to form distorted CaO7 pentagonal bipyramids that share a cornercorner with one CaO6 octahedra, corners with three PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Ca–O bond distances ranging from 2.29–2.63 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CaO6 octahedra, a cornercorner with one CaO7 pentagonal bipyramid, a cornercorner with one PO4 tetrahedra, and an edgeedge with one CaO7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 59°. There are a spread of P–O bond distances ranging from 1.52–1.65 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CaO6 octahedra, corners with two equivalent CaO7 pentagonal bipyramids, and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of P–O bond distances ranging from 1.52–1.65 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 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.75 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 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.73 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+, one P5+, and one H1+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to two Ca2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms.
