Materials Data on Ce3Sb3Au2 by Materials Project

Ce3Au2Sb3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to six Sb3- atoms to form a mixture of corner and edge-sharing CeSb6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (3.22 Å) and three longer (3.27 Å) Ce–Sb bond lengths. In the second Ce3+ site, Ce3+ is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Sb3- atoms. All Ce–Au bond lengths are 3.08 Å. All Ce–Sb bond lengths are 3.54 Å. Au is bonded in a 6-coordinate geometry to three equivalent Ce3+ and three equivalent Sb3- atoms. All Au–Sb bond lengths are 2.81 Å. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 6-coordinate geometry to six Ce3+ and three equivalent Au atoms. In the second Sb3- site, Sb3- is bonded to six equivalent Ce3+ atoms to form edge-sharing SbCe6 octahedra.
