The crystal structure described by LaRh2Ni3 crystallizes in the orthorhombic Cmmm space group. La(1) is bonded in a 18-coordinate geometry to eight equivalent Rh(1), four equivalent Ni(2), and six equivalent Ni(1) atoms. Rh(1) is bonded to four equivalent La(1), two equivalent Rh(1), two equivalent Ni(2), and four equivalent Ni(1) atoms to form distorted RhLa4Ni6Rh2 cuboctahedra that share corners with four equivalent Ni(2)La4Ni4Rh4 cuboctahedra, corners with twelve equivalent Rh(1)La4Ni6Rh2 cuboctahedra, edges with four equivalent Ni(2)La4Ni4Rh4 cuboctahedra, edges with six equivalent Rh(1)La4Ni6Rh2 cuboctahedra, faces with four equivalent Ni(2)La4Ni4Rh4 cuboctahedra, and faces with six equivalent Rh(1)La4Ni6Rh2 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent Rh(1), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded to four equivalent La(1), four equivalent Rh(1), and four equivalent Ni(1) atoms to form distorted NiLa4Ni4Rh4 cuboctahedra that share corners with eight equivalent Rh(1)La4Ni6Rh2 cuboctahedra, corners with eight equivalent Ni(2)La4Ni4Rh4 cuboctahedra, edges with two equivalent Ni(2)La4Ni4Rh4 cuboctahedra, edges with eight equivalent Rh(1)La4Ni6Rh2 cuboctahedra, faces with two equivalent Ni(2)La4Ni4Rh4 cuboctahedra, and faces with eight equivalent Rh(1)La4Ni6Rh2 cuboctahedra. is represented by the CIF card [CIF]
