Materials Data on YbGa7Au3 by Materials Project

YbAu3Ga7 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Yb is bonded in a 6-coordinate geometry to six equivalent Au and twelve equivalent Ga atoms. All Yb–Au bond lengths are 3.33 Å. There are six shorter (3.33 Å) and six longer (3.44 Å) Yb–Ga bond lengths. Au is bonded in a 9-coordinate geometry to two equivalent Yb and seven Ga atoms. There are a spread of Au–Ga bond distances ranging from 2.63–2.71 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a distorted trigonal planar geometry to two equivalent Yb and three equivalent Au atoms. In the second Ga site, Ga is bonded in a trigonal planar geometry to three equivalent Au atoms.
