In contrast to the already known P63/mmc space group that the MAX phases crystallize, it was demonstrated that the R 3¯m space group could better satisfy the experimental data. The lattice parameters are a = 0.305 64 nm, c = 4.818 46 nm in a hexagonal unit cell. UR - https://doi.org/10.1007/s40145-012-0034-9 DO - 10.1007/s40145-012-0034-9
