The compound described by LaRh2Ni3 crystallizes in the hexagonal P6/mmm space group. La(1) is bonded in a distorted hexagonal planar geometry to six equivalent Rh(1) and twelve equivalent Ni(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Ni(1) atoms. Ni(1) is bonded to four equivalent La(1), four equivalent Rh(1), and four equivalent Ni(1) atoms to form a mixture of distorted face, corner, and edge-sharing NiLa4Ni4Rh4 cuboctahedra. is represented by the CIF file [CIF]
