Structure
edit
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
editPalladium(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]
