YbCu3Ga2 crystallizes in the hexagonal P6/mmm space group. Yb(1) is bonded in a 18-coordinate geometry to twelve equivalent Cu(1) and six equivalent Ga(1) atoms. Cu(1) is bonded to four equivalent Yb(1), four equivalent Cu(1), and four equivalent Ga(1) atoms to form a mixture of edge, corner, and face-sharing CuYb4Ga4Cu4 cuboctahedra. Ga(1) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Cu(1) atoms.
