TiNbC2 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 Nb(1)C6 octahedra, edges with six equivalent Ti(1)C6 octahedra, and edges with six equivalent Nb(1)C6 octahedra. The corner-sharing octahedral tilt angles are 2°. Nb(1) is bonded to six equivalent C(1) atoms to form NbC6 octahedra that share corners with six equivalent Ti(1)C6 octahedra, edges with six equivalent Ti(1)C6 octahedra, and edges with six equivalent Nb(1)C6 octahedra. The corner-sharing octahedral tilt angles are 2°. C(1) is bonded to three equivalent Ti(1) and three equivalent Nb(1) atoms to form a mixture of corner and edge-sharing CTi3Nb3 octahedra. The corner-sharing octahedra are not tilted.
