(color online) (a) Volume optimization (E–V) curves for SrMg 2 X 2 compounds. E omax is the ground state of the SrMg₂Bi₂, while the equation of states of other compounds is also represented here by subtracting the ground state energy ( E 0 ) of the compounds from the ground state energy of SrMg₂Bi₂. (b) Phonon dispersions of SrMg 2 X 2 compounds.
