Title: Materials Data on Ce(AlAu)2 by Materials Project

Abstract

Ce(AuAl)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce is bonded in a 8-coordinate geometry to eight Au and eight Al atoms. There are four shorter (3.38 Å) and four longer (3.42 Å) Ce–Au bond lengths. There are four shorter (3.39 Å) and four longer (3.43 Å) Ce–Al bond lengths. There are two inequivalent Au sites. In the first Au site, Au is bonded to four equivalent Ce and four equivalent Al atoms to form distorted AuCe4Al4 tetrahedra that share corners with twelve equivalent AlCe4Au4 tetrahedra, edges with two equivalent AlCe4Au4 tetrahedra, edges with four equivalent AuCe4Al4 tetrahedra, and faces with four equivalent AuCe4Al4 tetrahedra. All Au–Al bond lengths are 2.59 Å. In the second Au site, Au is bonded in a 5-coordinate geometry to four equivalent Ce and five Al atoms. There are one shorter (2.51 Å) and four longer (2.61 Å) Au–Al bond lengths. There are two inequivalent Al sites. In the first Al site, Al is bonded to four equivalent Ce and four equivalent Au atoms to form distorted AlCe4Au4 tetrahedra that share corners with twelve equivalent AuCe4Al4 tetrahedra, edges with two equivalent AuCe4Al4 tetrahedra, edges with four equivalent AlCe4Au4 tetrahedra, and facesmore » with four equivalent AlCe4Au4 tetrahedra.
