Materials Data on YCo3Ni2 by Materials Project
YCo3Ni2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Y is bonded in a distorted hexagonal planar geometry to twelve equivalent Co and six equivalent Ni atoms. All Y–Co bond lengths are 3.15 Å. All Y–Ni bond lengths are 2.81 Å. Co is bonded to four equivalent Y, four equivalent Co, and four equivalent Ni atoms to form a mixture of edge, face, and corner-sharing CoY4Co4Ni4 cuboctahedra. All Co–Co bond lengths are 2.43 Å. All Co–Ni bond lengths are 2.45 Å. Ni is bonded in a 12-coordinate geometry to three equivalent Y and six equivalent Co atoms.
