The structure described by Sc3NiC4 crystallizes in the orthorhombic Immm 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 C(1) atoms. In the second Sc site, Sc(2) is bonded to eight equivalent C(1) atoms to form distorted face-sharing ScC8 hexagonal bipyramids. Ni(1) is bonded in a square co-planar geometry to four equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to two equivalent Sc(2), three equivalent Sc(1), one Ni(1), and one C(1) atom. is represented by the CIF card [CIF]
