The synthesis of [Rh-2(eta (5)-Cp)(2)(mu -H)(mu -PPh2)(2)]BF4 (2) by protonation reaction of the metal basic complex [Rh-2(eta (5)-Cp)(2)(mu -PPh2)(2)] (1) with tetrafluoroboric acid in diethyl ether is described. Complex salt 2 was obtained in high yield and fully characterized by spectroscopic means and X-ray crystal diffraction. Applying the isolobal analogy between H and the fragment Au(PPh3) as a synthetic strategy on the reaction of compound 2 with equimolar amounts of [Au(CH3)(PPh3)] in refluxing acetone resulted in the formation of the expected triangular cluster compound [Rh-2{mu -Au(PPh3)}(eta (5)-Cp)(2)(mu -PPh2)(2)]BF4 (3) in good yield. Metal cluster salt 3 was fully characterized by spectroscopic data and its molecular structure in the crystal was determined by X-ray diffraction. The structural comparison of the protonated dirhodium core in the cationic complex of 2 with the Rh2Au framework in 3 is in good accordance with the isolobal relation between H+ and Au+ because they share the respective same position in these closely related molecular structures.
