摘要：

The structural stability of the layered matlockite compound BaFCl has been studied under pressure to similar to 35 GPa. BaFCl is observed to undergo a reversible structural transition at about 22 GPa and the high-pressure phase has been identified to be monoclinic with space group P2(1)/m. The structural identification of the high-pressure phase was carried out by taking into account the fact that the interlayer bonding between the two similar Cl- layers is relatively weak compared to those between the other layers and intralayer bondings, thereby rendering the low-pressure structure unstable against the deformation under pressure.
