Title: Materials Data on K2FeH8(SO6)2 by Materials Project

Abstract

K2FeH8(SO6)2 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to one H1+ and eight O2- atoms. The K–H bond length is 2.94 Å. There are a spread of K–O bond distances ranging from 2.75–3.13 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to one H1+ and eight O2- atoms. The K–H bond length is 2.92 Å. There are a spread of K–O bond distances ranging from 2.75–3.09 Å. There are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.13–2.17 Å. In the second Fe2+ site, Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are four shorter (2.15 Å) and two longer (2.16 Å) Fe–O bond lengths. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond lengthmore » is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å.

There is three shorter (1.49 Å) and one longer (1.50 Å) S–O bond length. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two equivalent K1+, one Fe2+, and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two equivalent K1+, one Fe2+, and two equivalent H1+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two K1+, one Fe2+, and one S6+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two K1+, one Fe2+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Fe2+, and two H1+ atoms. In the ninth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Fe2+, and two H1+ atoms. In the tenth O2- site, O2- is bonded in a distorted water-like geometry to one Fe2+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one H1+, and one S6+ atom. In the thirteenth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one H1+, and one S6+ atom.« less
