The structure described by Sc2Ni crystallizes in the cubic Fd-3m space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to three equivalent Sc(1) and six equivalent Sc(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
