Ti3GeC2 is MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) and three equivalent C(1) atoms. In the second Ti site, Ti(2) is bonded to six equivalent C(1) atoms to form edge-sharing TiC6 octahedra. Ge(1) is bonded in a 6-coordinate geometry to six equivalent Ti(1) atoms. C(1) is bonded to three equivalent Ti(1) and three equivalent Ti(2) atoms to form a mixture of corner and edge-sharing CTi6 octahedra. The corner-sharing octahedra are not tilted.
