TiTaC2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Ti(1) is bonded to six equivalent C(1) atoms to form TiC6 octahedra that share corners with six equivalent Ta(1)C6 octahedra, edges with six equivalent Ti(1)C6 octahedra, and edges with six equivalent Ta(1)C6 octahedra. The corner-sharing octahedral tilt angles are 1°. Ta(1) is bonded to six equivalent C(1) atoms to form TaC6 octahedra that share corners with six equivalent Ti(1)C6 octahedra, edges with six equivalent Ti(1)C6 octahedra, and edges with six equivalent Ta(1)C6 octahedra. The corner-sharing octahedral tilt angles are 1°. C(1) is bonded to three equivalent Ti(1) and three equivalent Ta(1) atoms to form a mixture of edge and corner-sharing CTa3Ti3 octahedra. The corner-sharing octahedra are not tilted.
