Palladium(II) sulfide
Palladium(II) sulfide is a chemical compound of palladium and sulfur with the chemical formula PdS. Like other palladium and platinum chalcogenides, palladium(II) sulfide has complex structural, electrical and magnetic properties.
Palladium(II) sulfide is formed when hydrogen sulfide is passed through an aqueous solution containing palladium in the +2 oxidation state:
Berzelius reacted palladium directly with sulfur to produce palladium(II) sulfide in 1813:
The crystal structure of PdS contains approximately square planar palladium centres and tetrahedral sulfur centres.
If palladium(II) sulfide is heated with an excess of sulfur, palladium disulfide is formed:
A variety of other compounds in the Pd-S system have been reported, including Pd4S, Pd2.8S, Pd2.2S and PdS2. The mineral Braggite has the composition (Pt, Pd, Ni)S and is isomorphous with PdS.
