Materials Data on Rb2Fe2(PO4)3 by Materials Project
Abstract
Rb2Fe2(PO4)3 crystallizes in the cubic P2_13 space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Rb–O bond distances ranging from 2.94–3.19 Å. In the second Rb site, Rb is bonded in a 12-coordinate geometry to twelve O atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.32 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.02 Å) and three longer (2.04 Å) Fe–O bond lengths. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.01 Å) and three longer (2.03 Å) Fe–O bond lengths. P is bonded to four O atoms to form PO4 tetrahedra that share corners with four FeO6 octahedra. The corner-sharing octahedra tilt angles range from 13–47°. There is one shorter (1.54 Å) and three longer (1.55 Å) P–O bond length. There are four inequivalentmore »
