Title: Materials Data on Sr3Rh2O7 by Materials Project

Abstract

Sr3Rh2O7 crystallizes in the orthorhombic Ccce space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.44–2.77 Å. In the second Sr2+ site, Sr2+ is bonded in a 12-coordinate geometry to eight O2- atoms. There are four shorter (2.54 Å) and four longer (2.77 Å) Sr–O bond lengths. Rh4+ is bonded to six O2- atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 0–26°. There are a spread of Rh–O bond distances ranging from 2.01–2.07 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to five equivalent Sr2+ and one Rh4+ atom to form OSr5Rh octahedra that share corners with five OSr4Rh2 octahedra and edges with eight equivalent OSr5Rh octahedra. The corner-sharing octahedra tilt angles range from 0–6°. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Sr2+ and two equivalent Rh4+ atoms. In the third O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Rh4+ atoms to form a mixture of distorted cornermore » and edge-sharing OSr4Rh2 octahedra. The corner-sharing octahedral tilt angles are 0°.« less
