Infobox disclaimer and references

Platinum bromide is the chemical compound with the formula PtBr2. This dark green powder is a common precursor to other platinum-bromide compounds. Like palladium chloride and palladium bromide, it is a polymer that dissolves only in coordinating solvents or in the presence of donor ligands.

[edit] Illustrative use

Transition metal carbene complex of platinum can be prepared by heating platinum bromide with the imidazolium salt NHC precursors, and sodium acetate in dimethyl sulfoxide.[1]
