Palladium chalcogenide halides

Thiele and co-workers 389) prepared the only known palladium chalcogenide halides, PdTel and Pd Sels, by hydrothermal synthesis in HI (see Section II,D,2) at 300°C, starting with the elements. Crystalline PdzSelj is better obtained by reaction of Pdl2 with Se and an excess of iodine in a closed ampoule at 250°C (reaction time, 2 days). 

Only chalcogenide halides of palladium and platinum are mentioned in the literature.
