Sc2InC is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. Sc(1) is bonded in a 3-coordinate geometry to three equivalent In(1) and three equivalent C(1) atoms. In(1) is bonded to six equivalent Sc(1) and six equivalent In(1) atoms to form distorted InSc6In6 cuboctahedra that share corners with six equivalent In(1)Sc6In6 cuboctahedra, corners with six equivalent C(1)Sc6 octahedra, edges with six equivalent In(1)Sc6In6 cuboctahedra, edges with six equivalent C(1)Sc6 octahedra, and faces with six equivalent In(1)Sc6In6 cuboctahedra. The corner-sharing octahedral tilt angles are 21°. C(1) is bonded to six equivalent Sc(1) atoms to form CSc6 octahedra that share corners with six equivalent In(1)Sc6In6 cuboctahedra, edges with six equivalent In(1)Sc6In6 cuboctahedra, and edges with six equivalent C(1)Sc6 octahedra.
