In the second Yb site, Yb(2) is bonded in a 20-coordinate geometry to four equivalent Cu(1), four equivalent Cu(2), four equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(3) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded to one Yb(1), one Yb(2), one Cu(2), two equivalent Cu(1), one Ga(3), two equivalent Ga(1), two equivalent Ga(2), and two equivalent Ga(4) atoms to form distorted CuYb2Ga7Cu3 cuboctahedra that share corners with two equivalent Cu(1)Yb2Ga4Cu6 cuboctahedra, corners with four equivalent Ga(3)Yb2Ga8Cu2 cuboctahedra, corners with six equivalent Cu(2)Yb2Ga7Cu3 cuboctahedra, edges with two equivalent Cu(1)Yb2Ga4Cu6 cuboctahedra, edges with two equivalent Cu(2)Yb2Ga7Cu3 cuboctahedra, edges with two equivalent Ga(3)Yb2Ga8Cu2 cuboctahedra,  a faceface with one Yb(1)Ga12Cu8 cuboctahedra,  a faceface with one Ga(3)Yb2Ga8Cu2 cuboctahedra, faces with two equivalent Cu(1)Yb2Ga4Cu6 cuboctahedra, and faces with five equivalent Cu(2)Yb2Ga7Cu3 cuboctahedra.
