Abstract:
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 { M L n }‐C≡CC≡C‐{ M ′L′ m } [ M L n = Ru(dppe)Cp*, M ′L′ m = Fe(dppp)Cp* ( 1 ), Ru(dppe)Cp* ( 2 ), M L n = M ′L′ m = Os(PPh 3 ) 2 Cp ( 3 )], and {Cp*(dppe)Ru}C≡CC≡C{ trans ‐RuCl(dppe) 2 } ( 4 ), in which the alternating C(sp)–C(sp) bonds have values between 1.375 and 1.40 Å (single) and between 1.20 and 1.259 Å (triple), respectively, are described. In addition, a structure determination of Ru 3 (μ‐H){μ 3 ‐C 2 C≡C[Ru(PPh 3 ) 2 Cp]}(CO) 9 ( 5 ) shows that the C 2 fragment attached to the HRu 3 cluster shows the expected lengthening [to 1.311(7) Å] and bending at the two carbon atoms [to 152.6(6) and 157.6(5)°] (resulting from back‐bonding from the Ru 3 cluster into the C≡C π* orbitals) compared with the essentially linear Ru–CC– moiety [C≡C 1.222(6) Å, angles at C of 178.0(5), 172.3(6)°],
