Abstract
The product of the reaction of (π-C5 H5)Ru(PPh3)2 Cl and CuC2Ph has been characterized by single-crystal x-ray diffraction techniques and shown to have stoichiometry (π-C5 H5)Ru(PPh3)2Cu(C2Ph)Cl-(CH3)2CO(I). The compound contains a phenylethynyl group σ-bonded to the ruthenium atom and simultaneously π-bonded to a terminal Cu-Cl bond. Crystals of this compound from acetone are monoclinic,P21/c, witha = 12.914, = 22.111,c = 16.534 Å, β = 110.77 °, andZ — 4. Full-matrix least-squares refinement constraining the phenyl rings of the triphenylphosphines, the cyclopentadienyl ring, and the solvent of crystallization (acetone) as rigid groups yieldedR and weightedR values of 0.084 and 0.075, respectively.
