Structure

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]
