The material structure described by LaNi3Cu2 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a 18-coordinate geometry to twelve equivalent Ni(1) and six equivalent Cu(1) atoms. Ni(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 NiLa4Cu4Ni4 cuboctahedra. Cu(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Ni(1) atoms. is represented by the CIF file [CIF]
