title: Pressure-induced internal redox reaction of Cs2[PdI4].I2, Cs2[PdBr4].I2, and Cs2[PdCl4].I2.
abstract: The pressure-induced redox reaction within the system Cs2[Pd2+I4].I2/Cs2[Pd4+I6] was investigated by means of powder X-ray diffraction. Analogous high-pressure X-ray diffraction experiments were performed on the isostructural compounds Cs2[PdX4].I2 (X = Cl, Br). Additionally, the phase transition of Cs2[PdBr4].I2 to Cs2[PdBr4I2] was characterized by means of Raman scattering experiments as well as theoretical calculations based on density functional theory. On the basis of experimentally determined crystal structure data, a pathway for the topology of the redox reactions was developed and outlined.
