  摘要：

  The reaction of the Et2C2B4H5- monoanion with (Cp*RuCl)(4) in THF gave pale yellow, air-stable, crystalline Cp*RuH(Et2C2B4H4) (1H), which was characterized via NMR, IR, UV-visible, and mass spectroscopy and X-ray diffraction. The hydride ligand on ruthenium is monohapto, with an Ru-H bond distance of 1.55(8)Angstrom, and is protonic in character, being easily removed on treatment with t-butyllithium to afford the Cp*Ru(Et2C2B4H4)(-) monoanion (1). In an attempt to prepare an Ru-Me derivative, 1 was reacted with methyl triflate, but the only isolable product, unexpectedly, was a B-methylated species, Cp*(RuH)-H-II(Et2C2B4H3-5-Me) (2), obtained as a colorless air-stable solid and characterized via multinuclear, IR, UV-visible, and mass spectroscopy. Treatment of the cobaltcarborane monoanion Cp*Co(Et2C2B3H4)(-) with (Cp*RuCl)(4) in THF gave the heterobimetallic triple-decker sandwich Cp*Co(Et2C2B3H3)RuHCp* (4), a dark green diamagnetic crystalline solid, characterized spectroscopically as in the cases of the preceding compounds. Crystal data for 1H: space group P2(1)/c; a=12.598(3)Angstrom, b=8.674(2)Angstrom, c=16.772(6)Angstrom, beta=100.29(3)degrees,Z=4; R=0.043 for 2462 independent reflections having I>3 sigma(I).
