Title: Materials Data on NaCa2Al2P2H5O11F4 by Materials Project

Abstract

NaCa2Al2P2H5O11F4 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a 5-coordinate geometry to three O2- and two equivalent F1- atoms. There are a spread of Na–O bond distances ranging from 2.42–2.51 Å. Both Na–F bond lengths are 2.20 Å. Ca2+ is bonded in a 8-coordinate geometry to five O2- and three F1- atoms. There are a spread of Ca–O bond distances ranging from 2.43–2.64 Å. There are a spread of Ca–F bond distances ranging from 2.28–2.39 Å. Al3+ is bonded to four O2- and two F1- atoms to form AlO4F2 octahedra that share a cornercorner with one AlO4F2 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of Al–O bond distances ranging from 1.86–2.03 Å. There is one shorter (1.81 Å) and one longer (1.86 Å) Al–F bond length. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent AlO4F2 octahedra. The corner-sharing octahedral tilt angles are 56°. There are a spread of P–O bond distances ranging from 1.54–1.57 Å. In the second P5+ site, P5+more » is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent AlO4F2 octahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. There are three 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 0.99 Å. In the second 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 (1.66 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.64 Å) H–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two equivalent Ca2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+, one Al3+, and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Al3+, one P5+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ca2+, one Al3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ca2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Al3+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two equivalent Ca2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted tetrahedral geometry to one Na1+, one P5+, and two equivalent H1+ atoms. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and one Al3+ atom. In the second F1- site, F1- is bonded in a 3-coordinate geometry to one Na1+, one Ca2+, and one Al3+ atom.« less
