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.
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. There are two shorter (2.96 Å) and one longer (3.00 Å) Yb(1)-Au(1) bond length. In the second Yb site, Yb(2) is bonded in a distorted water-like geometry to two equivalent Au(1) atoms. Both Yb(2)-Au(1) bond lengths are 2.95 Å. In the third Yb site, Yb(3) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Au(1) atoms. All Yb(3)-Au(1) bond lengths are 2.91 Å. Au(1) is bonded in a 6-coordinate geometry to one Yb(3), two equivalent Yb(2), and three equivalent Yb(1) atoms.
