The crystal structure described by Yb(CuGa2)4 crystallizes in the orthorhombic Fmmm space group. Yb(1) is bonded in a 20-coordinate geometry to four equivalent Cu(1), four equivalent Cu(2), four equivalent Ga(1), and eight equivalent Ga(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent Yb(1), two equivalent Cu(1), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted edge, face, and corner-sharing CuYb2Ga8Cu2 cuboctahedra. In the second Cu site, Cu(2) is bonded to two equivalent Yb(1), two equivalent Cu(2), four equivalent Ga(1), and four equivalent Ga(2) atoms to form a mixture of distorted edge, face, and corner-sharing CuYb2Ga8Cu2 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Yb(1), two equivalent Cu(1), two equivalent Cu(2), one Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 12-coordinate geometry to two equivalent Yb(1), two equivalent Cu(1), two equivalent Cu(2), two equivalent Ga(2), and four equivalent Ga(1) atoms. is represented by the CIF file [CIF]
