Materials Data on SbH2SO3F7 by Materials Project
SbH2SO3F7 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two SbH2SO3F7 ribbons oriented in the (2, 0, 1) direction. Sb5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of Sb–F bond distances ranging from 1.89–1.98 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.05 Å. The H–F bond length is 1.43 Å. In the second H1+ site, H1+ is bonded in a linear geometry to one O2- and one F1- atom. The H–O bond length is 1.04 Å. The H–F bond length is 1.46 Å. S6+ is bonded in a tetrahedral geometry to three O2- and one F1- atom. There are a spread of S–O bond distances ranging from 1.41–1.51 Å. The S–F bond length is 1.56 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one S6+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Sb5+ and one H1+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Sb5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one S6+ atom. In the seventh F1- site, F1- is bonded in a bent 150 degrees geometry to one Sb5+ and one H1+ atom.
