Materials Data on Gd3OsO7 by Materials Project
Abstract
Gd3OsO7 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are six inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to seven O2- atoms to form distorted GdO7 pentagonal bipyramids that share corners with two OsO6 octahedra, corners with two equivalent GdO7 pentagonal bipyramids, and edges with two OsO6 octahedra. The corner-sharing octahedra tilt angles range from 42–49°. There are a spread of Gd–O bond distances ranging from 2.24–2.60 Å. In the second Gd3+ site, Gd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Gd–O bond distances ranging from 2.36–2.52 Å. In the third Gd3+ site, Gd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Gd–O bond distances ranging from 2.33–2.54 Å. In the fourth Gd3+ site, Gd3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Gd–O bond distances ranging from 2.28–2.75 Å. In the fifth Gd3+ site, Gd3+ is bonded to seven O2- atoms to form distorted GdO7 pentagonal bipyramids that share corners with two OsO6 octahedra, corners with two equivalent GdO7 pentagonal bipyramids, and edges with two OsO6 octahedra.
