Platinum(II) bromide
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(II) bromide, it is a compound that dissolves only in coordinating solvents or in the presence of donor ligands.
