Title: Materials Data on Gd4Au2O9 by Materials Project

Abstract

Gd4Au2O9 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing GdO7 pentagonal bipyramids. There are a spread of Gd–O bond distances ranging from 2.31–2.53 Å. In the second Gd3+ site, Gd3+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing GdO7 pentagonal bipyramids. There are a spread of Gd–O bond distances ranging from 2.32–2.58 Å. Au3+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Au–O bond distances ranging from 2.01–2.07 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to four Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra. In the second O2- site, O2- is bonded to three Gd3+ and one Au3+ atom to form distorted OGd3Au trigonal pyramids that share corners with seven OGd4 tetrahedra, corners with eight OGd3Au trigonal pyramids, an edgeedge with one OGd3Au tetrahedra, and edges with two OGd3Au trigonal pyramids. In the third O2- site, O2- is bonded to three Gd3+more » and one Au3+ atom to form distorted OGd3Au tetrahedra that share corners with three OGd4 tetrahedra, corners with ten OGd3Au trigonal pyramids, an edgeedge with one OGd4 tetrahedra, and edges with three OGd3Au trigonal pyramids. In the fourth O2- site, O2- is bonded to three Gd3+ and one Au3+ atom to form a mixture of distorted edge and corner-sharing OGd3Au trigonal pyramids. In the fifth O2- site, O2- is bonded to three Gd3+ and one Au3+ atom to form distorted OGd3Au trigonal pyramids that share corners with six OGd4 tetrahedra, corners with nine OGd3Au trigonal pyramids, an edgeedge with one OGd3Au tetrahedra, and edges with two OGd3Au trigonal pyramids.« less
