Materials Data on K2FeH4(SO5)2 by Materials Project
Abstract
K2FeH4(SO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.84–3.25 Å. Fe2+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 2.13–2.18 Å. There are two 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 one O2- atom. The H–O bond length is 0.99 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 44–48°. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one Fe2+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to twomore »
