The material structure described by (Cr0.5V0.5)2GeC is MAX Phase-derived structured and crystallizes in the trigonal P-3m1 space group. V(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) and three equivalent C(2) atoms. Cr(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) and three equivalent C(1) atoms. Ge(1) is bonded in a 6-coordinate geometry to three equivalent V(1) and three equivalent Cr(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to six equivalent Cr(1) atoms to form edge-sharing CCr6 octahedra. In the second C site, C(2) is bonded to six equivalent V(1) atoms to form edge-sharing CV6 octahedra. is represented by the CIF card [CIF]
