A high-pressure phase of MgC2. The crystal structure of MgC2 at 150 GPa with solid lines showing the unit-cell. (a) Top view and (b) side view. (c) Band structure of MgC2 and (d) stable phonon dispersion curve at 150 GPa. We chose the continuous Γ-M-K-Γ-A-L-H-A path followed by discontinuous M-L and K-H paths.
