Materials Data on Er5SbAu2 by Materials Project
Er5Au2Sb crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded to four equivalent Au and two equivalent Sb atoms to form corner-sharing ErSb2Au4 octahedra. The corner-sharing octahedra tilt angles range from 0–49°. All Er–Au bond lengths are 3.13 Å. Both Er–Sb bond lengths are 3.23 Å. In the second Er site, Er is bonded in a 5-coordinate geometry to three equivalent Au and two equivalent Sb atoms. All Er–Au bond lengths are 3.00 Å. Both Er–Sb bond lengths are 3.34 Å. Au is bonded in a 8-coordinate geometry to eight Er atoms. Sb is bonded in a distorted q6 geometry to ten Er atoms.
