  Alkyne Coupling Induced by a Trinuclear Ruthenium Cluster: Synthesis and Structure of Di-μ-carbonyl-hexacarbonyl-μ3-(1,2,3,4-tetraphenyl-1,3-butadiene-1,4-diyl)-triruthenium(2 Ru—Ru), [Ru3(CO)8(C4Ph4)]

  摘要：

  The reaction of PhC=CPh with [Ru-3(CO)(10)(MeCN)(2)] affords two [Ru-3(CO)(8)(C(2)Ph(2))(2)] complexes, one red-violet containing only terminal carbonyl groups and the other the orange-yellow title compound, di-mu-carbonyl-1:2 kappa(2)C;1:3 kappa(2)C-hexacarbonyl-1 kappa(2)C,3 kappa(2)C-mu(3)-[1,2,3,4-tetraphenyl-2(eta(4)):3(eta(4))-1,3-butadiene-1,4-diyl-1 kappa(2)C]-triruthenium(2 Ru-Ru). The structure of the latter isomer consists of an open Ru-3 cluster [Ru-Ru 2.6696(8) and 2.6717 (6), Ru ... Ru 3.7461 (7) Angstrom] coordinated to the C(4)Ph(4) ligand, formed by the dimerization of PhC=CPh, and to eight CO groups, six terminal and two bridging. The central Ru atom is sigma-bonded to the butadiene moiety to form an RuC4 metallacyclopentadiene ring [Ru-C 2.219(4) and 2.216(4); mean C-C 1.461 Angstrom]. Each of the other two metal atoms is eta(4)-bonded to the C atoms of the RuC4 ring [mean Ru-C 2.322 Angstrom] to form a pentagonal bipyramidal Ru3C4 core.
