Materials Data on Nd4Au2O9 by Materials Project
Nd4Au2O9 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to seven O2- atoms to form a mixture of distorted corner and edge-sharing NdO7 pentagonal bipyramids. There are a spread of Nd–O bond distances ranging from 2.37–2.56 Å. In the second Nd3+ site, Nd3+ is bonded to seven O2- atoms to form a mixture of distorted corner and edge-sharing NdO7 pentagonal bipyramids. There are a spread of Nd–O bond distances ranging from 2.37–2.63 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 three Nd3+ and one Au3+ atom to form a mixture of distorted corner and edge-sharing ONd3Au trigonal pyramids. In the second O2- site, O2- is bonded to three Nd3+ and one Au3+ atom to form distorted ONd3Au tetrahedra that share corners with three ONd3Au tetrahedra, corners with seven ONd3Au trigonal pyramids, an edgeedge with one ONd4 tetrahedra, and edges with two ONd3Au trigonal pyramids. In the third O2- site, O2- is bonded to three Nd3+ and one Au3+ atom to form distorted ONd3Au trigonal pyramids that share corners with six ONd4 tetrahedra, corners with three equivalent ONd3Au trigonal pyramids, an edgeedge with one ONd3Au tetrahedra, and edges with two ONd3Au trigonal pyramids. In the fourth O2- site, O2- is bonded to four Nd3+ atoms to form a mixture of corner and edge-sharing ONd4 tetrahedra. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three Nd3+ and one Au3+ atom.
