20. Theoretical calculations (Ref. 3) reveal several candidates for the high-pressures phase. All three-coordinated structures can be obtained by distortion of a simple cubic phase (sixfold coordinated which is unstable) and are related to phonon instabilities in different high-symmetry points of the Brillouin zone (Ref. 20).
