The crystal structure described by YMgCo2Ni2 is Hexagonal Laves-derived structured and crystallizes in the orthorhombic Imm2 space group. Mg(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 Mg(1), six equivalent Co(1), and six equivalent Ni(1) atoms. Co(1) is bonded to three equivalent Mg(1), three equivalent Y(1), two equivalent Co(1), and four equivalent Ni(1) atoms to form CoY3Mg3Co2Ni4 cuboctahedra that share corners with eight equivalent Ni(1)Y3Mg3Co4Ni2 cuboctahedra, corners with ten equivalent Co(1)Y3Mg3Co2Ni4 cuboctahedra, edges with six equivalent Co(1)Y3Mg3Co2Ni4 cuboctahedra, faces with six equivalent Co(1)Y3Mg3Co2Ni4 cuboctahedra, and faces with twelve equivalent Ni(1)Y3Mg3Co4Ni2 cuboctahedra. Ni(1) is bonded to three equivalent Mg(1), three equivalent Y(1), four equivalent Co(1), and two equivalent Ni(1) atoms to form NiY3Mg3Co4Ni2 cuboctahedra that share corners with eight equivalent Co(1)Y3Mg3Co2Ni4 cuboctahedra, corners with ten equivalent Ni(1)Y3Mg3Co4Ni2 cuboctahedra, edges with six equivalent Ni(1)Y3Mg3Co4Ni2 cuboctahedra, faces with six equivalent Ni(1)Y3Mg3Co4Ni2 cuboctahedra, and faces with twelve equivalent Co(1)Y3Mg3Co2Ni4 cuboctahedra. is represented by the CIF card [CIF]
