Abstract

Abstract The synthesis and X-ray characterization of binuclear dipalladium(I) and diplatinum(I) p-xylene complexes [Pd 2(η 6-C 8H 10) 2(μ-Cl/Br) 2(GaCl 3) 2] ( 1) and [Pt 2(η 6-C 8H 10) 2(Ga 2Br 7) 2] ( 5) are reported. It was established that the toluene ligands in the palladium complex [Pd 2(η 6-C 7H 8) 2(GaCl 4) 2] ( 3) can be substituted by naphthalene without disruption of the metal–metal bond. The reaction of 3 with Pd(PPh 3) 4 leads to the formation of a dipalladium(II) μ-diphenylphosphido compound [Pd 2(μ-PPh 2)(PPh 3) 4] (GaCl 4) 2 · 4(C 7H 8) ( 4), most likely also involving a bridging μ-H − ligand.
