Materials Data on EuAsAu by Materials Project
EuAuAs 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 As3- atoms to form a mixture of face and edge-sharing EuAs6Au6 cuboctahedra. All Eu–Au bond lengths are 3.32 Å. All Eu–As bond lengths are 3.32 Å. Au1+ is bonded in a 3-coordinate geometry to six equivalent Eu2+ and three equivalent As3- atoms. All Au–As bond lengths are 2.60 Å. As3- is bonded in a 3-coordinate geometry to six equivalent Eu2+ and three equivalent Au1+ atoms.
