Materials Data on ErAs by Materials Project

ErAs is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Er3+ is bonded to six equivalent As3- atoms to form a mixture of edge and corner-sharing ErAs6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Er–As bond lengths are 2.89 Å. As3- is bonded to six equivalent Er3+ atoms to form a mixture of edge and corner-sharing AsEr6 octahedra. The corner-sharing octahedral tilt angles are 0°.
