The material described by ErSm(Co2Ni3)2 crystallizes in the orthorhombic Pmmm space group. Er(1) is bonded in a 18-coordinate geometry to two equivalent Co(1), four equivalent Co(2), four equivalent Ni(2), and eight equivalent Ni(3) atoms. Sm(1) is bonded in a 18-coordinate geometry to two equivalent Co(2), four equivalent Co(1), four equivalent Ni(1), and eight equivalent Ni(3) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to one Er(1), two equivalent Sm(1), two equivalent Ni(1), and four equivalent Ni(3) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Er(1), one Sm(1), two equivalent Ni(2), and four equivalent Ni(3) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to four equivalent Sm(1), four equivalent Co(1), and four equivalent Ni(3) atoms to form NiSm4Co4Ni4 cuboctahedra that share corners with four equivalent Ni(2)Er4Co4Ni4 cuboctahedra, corners with four equivalent Ni(1)Sm4Co4Ni4 cuboctahedra, corners with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra, edges with two equivalent Ni(1)Sm4Co4Ni4 cuboctahedra, edges with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra, faces with two equivalent Ni(1)Sm4Co4Ni4 cuboctahedra, and faces with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra. In the second Ni site, Ni(2) is bonded to four equivalent Er(1), four equivalent Co(2), and four equivalent Ni(3) atoms to form NiEr4Co4Ni4 cuboctahedra that share corners with four equivalent Ni(2)Er4Co4Ni4 cuboctahedra, corners with four equivalent Ni(1)Sm4Co4Ni4 cuboctahedra, corners with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra, edges with two equivalent Ni(2)Er4Co4Ni4 cuboctahedra, edges with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra, faces with two equivalent Ni(2)Er4Co4Ni4 cuboctahedra, and faces with eight equivalent Ni(3)Sm2Er2Co4Ni4 cuboctahedra.
