The material structure described by SmY(CoNi)2 is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imm2 space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Y(1), six equivalent Co(1), and six equivalent Ni(1) atoms. Y(1) is bonded in a 16-coordinate geometry to four equivalent Sm(1), six equivalent Co(1), and six equivalent Ni(1) atoms. Co(1) is bonded to three equivalent Sm(1), three equivalent Y(1), two equivalent Co(1), and four equivalent Ni(1) atoms to form CoSm3Y3Co2Ni4 cuboctahedra that share corners with eight equivalent Ni(1)Sm3Y3Co4Ni2 cuboctahedra, corners with ten equivalent Co(1)Sm3Y3Co2Ni4 cuboctahedra, edges with six equivalent Co(1)Sm3Y3Co2Ni4 cuboctahedra, faces with six equivalent Co(1)Sm3Y3Co2Ni4 cuboctahedra, and faces with twelve equivalent Ni(1)Sm3Y3Co4Ni2 cuboctahedra. Ni(1) is bonded to three equivalent Sm(1), three equivalent Y(1), four equivalent Co(1), and two equivalent Ni(1) atoms to form NiSm3Y3Co4Ni2 cuboctahedra that share corners with eight equivalent Co(1)Sm3Y3Co2Ni4 cuboctahedra, corners with ten equivalent Ni(1)Sm3Y3Co4Ni2 cuboctahedra, edges with six equivalent Ni(1)Sm3Y3Co4Ni2 cuboctahedra, faces with six equivalent Ni(1)Sm3Y3Co4Ni2 cuboctahedra, and faces with twelve equivalent Co(1)Sm3Y3Co2Ni4 cuboctahedra. is represented by the CIF file [CIF]
