LaNi2Cu3 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 18-coordinate geometry to six equivalent Ni(1) and twelve equivalent Cu(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Cu(1) atoms. Cu(1) is bonded to four equivalent La(1), four equivalent Ni(1), and four equivalent Cu(1) atoms to form a mixture of edge, corner, and face-sharing CuLa4Cu4Ni4 cuboctahedra.
