Palladium(II) sulfide is formed when hydrogen sulfide is passed through an aqueous solution containing palladium in the +2 oxidation state:[2]
Berzelius reacted palladium directly with sulfur to produce palladium(II) sulfide in 1813:[4]
The crystal structure of PdS contains approximately square planar palladium centres and tetrahedral sulfur centres.[1]
If palladium(II) sulfide is heated with an excess of sulfur, palladium disulfide is formed:[2]
A variety of other compounds in the Pd-S system have been reported, including Pd4S, Pd2.8S, Pd2.2S and PdS2.[4] The mineral Braggite has the composition (Pt, Pd, Ni)S and is isomorphous with PdS.[3]
