Fig. 7: Hypothetical crystal structure and corresponding electronic structure of Re₃Ge₆Ga.

a The primitive cell for Re₃Ge₇ and a possible C2/m configuration of Re₃Ge₆Ga. b Bulk band structure for Re₃Ge₆Ga with space group C2/m. The cyan and yellow regions correspond to the band filling of x = 0 and 1, respectively.
