UCu3Al2 crystallizes in the hexagonal P6/mmm space group. U(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 U(1) and four equivalent Al(1) atoms to form a mixture of distorted face, corner, and edge-sharing CuU4Al4 cuboctahedra. Al(1) is bonded in a 6-coordinate geometry to three equivalent U(1) and six equivalent Cu(1) atoms.
