TaVC2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ta(1) is bonded to six equivalent C(1) atoms to form TaC6 octahedra that share corners with six equivalent V(1)C6 octahedra, edges with six equivalent Ta(1)C6 octahedra, and edges with six equivalent V(1)C6 octahedra. The corner-sharing octahedral tilt angles are 3°. V(1) is bonded to six equivalent C(1) atoms to form VC6 octahedra that share corners with six equivalent Ta(1)C6 octahedra, edges with six equivalent Ta(1)C6 octahedra, and edges with six equivalent V(1)C6 octahedra. The corner-sharing octahedral tilt angles are 3°. C(1) is bonded to three equivalent Ta(1) and three equivalent V(1) atoms to form a mixture of corner and edge-sharing CTa3V3 octahedra. The corner-sharing octahedra are not tilted.
