Abstract

The compound [RuH(CO)25-C5H5)] formed in situ during the reaction of [Ru3(CO)12] with cyclopentadiene has been found to add in a stereo- and regio-specific manner to endo-dicyclopentadiene to afford the alkyl derivative [Ru(C10H13)(CO)25-C 5H5)] which undergoes a facile carbonylation to the acyl complex [Ru(COC10H13)-(CO)25-C 5H5)]. The structure of [Ru(COC10H13)(CO)25-C 5H5)] was determined by a single-crystal X-ray diffraction analysis; crystals are triclinic, space group P1, a = 6.342(1), b = 7.144(2), c = 81.491(4) Å, α = 86.65(3), β = 85.98(4), γ = 71.41(2)°, and Z = 2. The final R value was 0.034 for 2402 observed reflections.

Funding Information:
Thestructure was solved by the heavy-atom technique using2 402 unique reflections with F, > 34F0). Full-matrixleast-squares refinement of all atomic positions convergedto a conventional R and weighted R' factors of 0.034 and0.035, respectively [w = 1.5484/02(F0) + 0.001(F0)2].* Allcalculations were performed with the SHELX-76 lo pack-age of crystallographic programs. Final atomic co-ordinatesare listed in Table 2.
