Materials Data on SmCo3Ni2 by Materials Project
SmCo3Ni2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sm is bonded in a distorted hexagonal planar geometry to twelve equivalent Co and six equivalent Ni atoms. All Sm–Co bond lengths are 3.18 Å. All Sm–Ni bond lengths are 2.84 Å. Co is bonded to four equivalent Sm, four equivalent Co, and four equivalent Ni atoms to form a mixture of corner, edge, and face-sharing CoSm4Co4Ni4 cuboctahedra. All Co–Co bond lengths are 2.46 Å. All Co–Ni bond lengths are 2.47 Å. Ni is bonded in a 12-coordinate geometry to three equivalent Sm and six equivalent Co atoms.
