YCo3Ni2 crystallizes in the hexagonal P6/mmm space group. Y(1) is bonded in a distorted hexagonal planar geometry to twelve equivalent Co(1) and six equivalent Ni(1) atoms. Co(1) is bonded to four equivalent Y(1), four equivalent Co(1), and four equivalent Ni(1) atoms to form a mixture of edge, face, and corner-sharing CoY4Co4Ni4 cuboctahedra. Ni(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Co(1) atoms.
