Synthesis and crystal structure of twisted dinuclear η3-allylpalladium complexes containing tetradentate nitrogen ligands

The dinuclear palladium allyl complexes 7 and 12, which contain tetradentate nitrogen ligands 2 or 3 as bridging ligands, respectively, were synthesized and characterized. Crystal X-ray analysis of these complexes reveal that the two coordination planes of the palladium are twisted, although each of the coordination spheres presents roughly the same structural features as the related (bipyridine)allylpalladium complex.
