YbCu3Al2 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 Al(1) atoms. Cu(1) is bonded to four equivalent Yb(1) and four equivalent Al(1) atoms to form a mixture of distorted corner, edge, and face-sharing CuYb4Al4 cuboctahedra. Al(1) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Cu(1) atoms.
