Materials Data on SrTiH4(OF3)2 by Materials Project

Abstract

SrTiH4(OF3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to three O2- and five F1- atoms. There are a spread of Sr–O bond distances ranging from 2.66–2.72 Å. There are a spread of Sr–F bond distances ranging from 2.48–2.52 Å. Ti4+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Ti–F bond distances ranging from 1.88–1.92 Å. There are four 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 single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third 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 fourth 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 two inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Sr2+ and two H1+ atoms. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Ti4+ atom. In the second F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Ti4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Ti4+ atom. In the fourth F1- site, F1- is bonded in a bent 150 degrees geometry to one Sr2+ and one Ti4+ atom. In the fifth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Ti4+ atom. In the sixth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Sr2+ and one Ti4+ atom.
