Palladium(II) bromide is an inorganic compound of palladium and bromine with the chemical formula PdBr<sub>2</sub>. It is a commercially available, although less common than palladium(II) chloride, the usual entry point to palladium complexes. It is a diamagnetic solid.
As confirmed by X-ray crystallography, PdBr<sub>2</sub> is a coordination polymer. It crystallises in the P2<sub>1</sub>/c space group and the structure consists of wavy ribbons of edge-sharing PdBr<sub>4</sub> coordination squares.
Palladium(II) bromide is insoluble in water but dissolves when heated in acetonitrile to give monomeric acetonitrile adducts:
PdBr<sub>2</sub> exhibits many of the properties of palladium chloride and palladium acetate, giving catalysts active for carbonylations and cross-coupling reactions.
