The structure described by TbCo2Ni3 crystallizes in the orthorhombic Cmmm space group. Tb(1) is bonded in a 18-coordinate geometry to eight equivalent Co(1), four equivalent Ni(1), and six equivalent Ni(2) atoms. Co(1) is bonded to four equivalent Tb(1), two equivalent Co(1), two equivalent Ni(1), and four equivalent Ni(2) atoms to form CoTb4Co2Ni6 cuboctahedra that share corners with four equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, corners with twelve equivalent Co(1)Tb4Co2Ni6 cuboctahedra, edges with four equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, edges with six equivalent Co(1)Tb4Co2Ni6 cuboctahedra, faces with four equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, and faces with six equivalent Co(1)Tb4Co2Ni6 cuboctahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Tb(1), four equivalent Co(1), and four equivalent Ni(2) atoms to form NiTb4Co4Ni4 cuboctahedra that share corners with eight equivalent Co(1)Tb4Co2Ni6 cuboctahedra, corners with eight equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, edges with two equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, edges with eight equivalent Co(1)Tb4Co2Ni6 cuboctahedra, faces with two equivalent Ni(1)Tb4Co4Ni4 cuboctahedra, and faces with eight equivalent Co(1)Tb4Co2Ni6 cuboctahedra. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to three equivalent Tb(1), four equivalent Co(1), and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
