Materials Data on Yb7Au3 by Materials Project
Yb7Au3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Yb sites. In the first Yb site, Yb is bonded in a distorted trigonal non-coplanar geometry to three equivalent Au atoms. All Yb–Au bond lengths are 2.96 Å. In the second Yb site, Yb is bonded in a distorted water-like geometry to two equivalent Au atoms. Both Yb–Au bond lengths are 3.00 Å. In the third Yb site, Yb is bonded in a 3-coordinate geometry to three equivalent Au atoms. There are two shorter (3.00 Å) and one longer (3.06 Å) Yb–Au bond lengths. Au is bonded in a 6-coordinate geometry to six Yb atoms.
