The compound described by Sc2CO is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sc(1) is bonded to three equivalent C(1) and three equivalent O(1) atoms to form a mixture of corner and edge-sharing ScC3O3 octahedra. The corner-sharing octahedra are not tilted. C(1) is bonded to six equivalent Sc(1) atoms to form CSc6 octahedra that share corners with six equivalent O(1)Sc6 octahedra, edges with six equivalent C(1)Sc6 octahedra, and edges with six equivalent O(1)Sc6 octahedra. The corner-sharing octahedral tilt angles are 2°. O(1) is bonded to six equivalent Sc(1) atoms to form OSc6 octahedra that share corners with six equivalent C(1)Sc6 octahedra, edges with six equivalent C(1)Sc6 octahedra, and edges with six equivalent O(1)Sc6 octahedra. The corner-sharing octahedral tilt angles are 2°. is represented by the Crystallographic Information File (CIF) [CIF]
