Rhombohedral phase showed phase transition to three-dimensional polymers above 10 GPa similar to experiments where isobaric heating was used at pressures 9 to 13 GPa. Tetragonal polymer exhibited significantly stronger stability and can be followed at least up to $\ensuremath{\sim}15\mathrm{GPa}.$ Heating up to 800 K of the tetragonal polymer at pressures 6 to 8 GPa confirms that due to geometrical frustrations tetragonal phase remains stable even at $P--T$ conditions where rhombohedral polymer is usually formed from orthorhombic chain polymers.Read More
