The elastic constants and phonon dispersion of metallic C[Formula: see text] are calculated by first-principles calculations. The results show that the metallic C[Formula: see text] is mechanically and dynamically stable under high pressure. The variations of G/B ratio, Poisson’s ratio, elastic anisotropy, acoustic velocity and Debye temperature at the pressure range from 0 GPa to 100 GPa are analyzed. The results reveal that by adjusting the pressures the elastic anisotropy and thermodynamic properties could be improved for better applicability.

First-principles calculations have been performed to investigate the structural stability, elastic, lattice dynamic, and thermodynamic properties of Na2Se under high pressure. Our results demonstrate that Na2Se in the antifluorite structure phase keeps dynamically stable until 30 GPa. The elastic constants and thermodynamic quantities under high pressure are also calculated and discussed.
