Reaction of PdCl2 with excess of GaCl3 in aromatic solvents leads to binuclear compounds of the general formula [Pd2X2(arene)(2)], where arene = C6H6, X- = GaCl7- (1); arene = C7H8, X- = GaCl4- (2). The solid-state structures of compounds 1 and 2 have been determined by X-ray crystallography. Two molecules of the arene are bound to the dipalladium unit. The compounds 1 and 2 do not react with triphenyl phosphine. Reaction of carbon monoxide with 1 in benzene solution yields [Pd-2(GaCl4)(2)(C6H6)(2)] (3), for which the crystal structure has also been determined. The compound [Pt-2(GaCl4)(2)(C10H10)(2)].2C(6)H(6) (4), which was obtained by reaction of K-2[PtCl4] with GaCl3 and naphthalene in a benzene solution, has a similar structure in the solid state.
