Description

PbCl2, SnCl2, BaCl2 and BaI2 all fall into a category of crystals known at AX2 compounds. At ambient pressure, these materials are analogue compounds that crystallize at ambient conditions in the cotunnite (orthorhombic, Pnam) structure. The next phase (post-cotunnite (monoclinic, P1121/a)) is claimed to be the final step in the structural sequence for AX2 compounds by Leger et al [1]. This holds significance because these compunds are iso-sturctural with a high pressure phase of silica, which is believed to be the primary component of rocky exoplanets.
