In the second Cu site, Cu is bonded in a 12-coordinate geometry to three equivalent Yb, six Cu, and three equivalent Al atoms. All Cu–Cu bond lengths are 2.72 Å. All Cu–Al bond lengths are 2.52 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a body-centered cubic geometry to eight equivalent Cu atoms. In the second Al site, Al is bonded to four equivalent Yb and eight Cu atoms to form a mixture of distorted face and corner-sharing AlYb4Cu8 cuboctahedra.
