Palladium(II) bromide is an inorganic compound of palladium and bromine with the chemical formula PdBr2. It is a commercially available, although less common than palladium(II) chloride, the usual entry point to palladium complexes. It is a diamagnetic solid.

Structure

3D model of a ribbon in the crystal structure of palladium(II) bromide

As confirmed by X-ray crystallography, PdBr2 is a coordination polymer.[1] It crystallises in the P21/c space group and the structure consists of wavy ribbons of edge-sharing PdBr4 coordination squares.[2]

Reactions

Palladium(II) bromide is insoluble in water but dissolves when heated in acetonitrile to give monomeric acetonitrile adducts:[3]

PdBr2 + 2 MeCN → PdBr2(MeCN)2

PdBr2 exhibits many of the properties of palladium chloride and palladium acetate, giving catalysts active for carbonylations and cross-coupling reactions.[4]
