Abstract

Hexagonal Ag₃YCl₆ was found to transform into a new phase by applying pressure above ∼1.5 GPa via a diamond anvil cell. In situ XRD analysis revealed that the phase is monoclinic Ag₃YCl₆. The bulk modulus of the hexagonal and monoclinic phases was 37 GPa and 49 GPa, respectively. Computational investigations also supported this phase transition and bulk modulus. After releasing pressure from 2 GPa, the diffraction peaks of hexagonal Ag₃YCl₆ were detected, indicating the reversibility of this phase transformation.
