The material structure described by Yb7Au3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 3-coordinate geometry to three equivalent Au(1) atoms. In the second Yb site, Yb(2) is bonded in a distorted water-like geometry to two equivalent Au(1) atoms. In the third Yb site, Yb(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Au(1) atoms. Au(1) is bonded in a 6-coordinate geometry to one Yb(3), two equivalent Yb(2), and three equivalent Yb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
