Materials Data on SmCo2Ni3 by Materials Project
SmCo2Ni3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Sm is bonded in a 6-coordinate geometry to six equivalent Co and twelve equivalent Ni atoms. All Sm–Co bond lengths are 2.83 Å. All Sm–Ni bond lengths are 3.16 Å. Co is bonded in a 12-coordinate geometry to three equivalent Sm and six equivalent Ni atoms. All Co–Ni bond lengths are 2.44 Å. Ni is bonded to four equivalent Sm, four equivalent Co, and four equivalent Ni atoms to form a mixture of corner, edge, and face-sharing NiSm4Co4Ni4 cuboctahedra. All Ni–Ni bond lengths are 2.45 Å.
