Palladium(II) fluorides with formula PdM^IVF₆ (M^IV≡Zr, Sn, Hf) exhibiting an ordered LiSbF₆ type structure (R3ˉ space group) were synthesized. A structural phase transition was detected using microdifferential thermal analysis, microcalorimetry and X-ray diffraction. The thermal dependence of the spontaneous strain was determined. A cubic Fm3ˉm high-temperature form was characterized for PdZrF₆ and PdHfF₆. The three phases show antiferromagnetic behavior.
