Materials Data on Rb2Fe2(SO4)3 by Materials Project
Abstract
Rb2Fe2(SO4)3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.25 Å. In the second Rb1+ site, Rb1+ is bonded in a 12-coordinate geometry to fifteen O2- atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.52 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.14 Å) and three longer (2.15 Å) Fe–O bond lengths. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six equivalent SO4 tetrahedra. All Fe–O bond lengths are 2.16 Å. S+5.33+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four FeO6 octahedra. The corner-sharing octahedra tilt angles range from 13–48°. There is one shorter (1.48 Å) and three longer (1.49 Å) S–O bond length. There are four inequivalent O2- sites. In the first O2- site,more »
