摘要：

As part of an extensive investigation into the chemistry of complexes containing metal-ligand centers linked by chains of C(sp) atoms, the preparation, characterization, and single-crystal X-ray diffraction molecular structure determinations of four complexes {MLn}-CCCC-{MLm} [MLn = Ru(dppe)Cp*, MLm = Fe(dppp)Cp* (1), Ru(dppe)Cp* (2), MLn = MLm = Os(PPh3)(2)Cp (3)], and {Cp*(dppe)Ru}CCCC{trans-RuCl(dppe)(2)} (4), in which the alternating C(sp)-C(sp) bonds have values between 1.375 and 1.40 angstrom (single) and between 1.20 and 1.259 angstrom (triple), respectively, are described. In addition, a structure determination of Ru-3(-H){(3)-C2CC[Ru(PPh3)(2)Cp]}(CO)(9) (5) shows that the C-2 fragment attached to the HRu3 cluster shows the expected lengthening [to 1.311(7) angstrom] and bending at the two carbon atoms [to 152.6(6) and 157.6(5)degrees] (resulting from back-bonding from the Ru-3 cluster into the CC * orbitals) compared with the essentially linear Ru-CC- moiety [CC 1.222(6) angstrom, angles at C of 178.0(5), 172.3(6)degrees],
