Materials Data on Eu3OsO7 by Materials Project
Eu3OsO7 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Eu3+ sites. In the first Eu3+ site, Eu3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.38 Å) and four longer (2.78 Å) Eu–O bond lengths. In the second Eu3+ site, Eu3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Eu–O bond distances ranging from 2.28–2.86 Å. Os5+ is bonded to six O2- atoms to form corner-sharing OsO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There is two shorter (1.92 Å) and four longer (1.93 Å) Os–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Eu3+ and two equivalent Os5+ atoms. In the second O2- site, O2- is bonded to four Eu3+ atoms to form a mixture of edge and corner-sharing OEu4 tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Eu3+ and one Os5+ atom.
