New rhenium carbonyl cluster complexes containing bridging hydrocarbyl and bridging mercury groups

The rhenium-mercury complexes [Re2(CO)8(μ-HgI)(μ-η1-C6H5)]2, 2 and [Re2(CO)8[μ-HCC(H)C4H9]2(μ4-Hg), 3 were obtained from the reactions of Re2(CO)8[μ-Au(PPh3)](μ-η1-C6H5), 1 with HgI2 and from Re2(CO)8[μ-HCC(H)C4H9](μ-H) with Hg(C6H5)2.
