Materials Data on EuSbAu by Materials Project

EuAuSb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Eu2+ is bonded to six equivalent Au1+ and six equivalent Sb3- atoms to form a mixture of face and edge-sharing EuSb6Au6 cuboctahedra. All Eu–Au bond lengths are 3.45 Å. All Eu–Sb bond lengths are 3.45 Å. Au1+ is bonded in a distorted trigonal planar geometry to six equivalent Eu2+ and three equivalent Sb3- atoms. All Au–Sb bond lengths are 2.74 Å. Sb3- is bonded in a 3-coordinate geometry to six equivalent Eu2+ and three equivalent Au1+ atoms.
