The structure described by Eu3Au2 crystallizes in the trigonal R-3 space group. There are three inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in an octahedral geometry to six equivalent Au(1) atoms. In the second Eu site, Eu(2) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. In the third Eu site, Eu(3) is bonded in a 5-coordinate geometry to five equivalent Au(1) atoms. Au(1) is bonded in a 8-coordinate geometry to one Eu(1), two equivalent Eu(2), and five equivalent Eu(3) atoms. is represented by the CIF file [CIF]
