Thermal treatment of the trinuclearruthenium complex μ2-η5:η1-(C5H4N)(C9H5)}Ru3(CO)9 (1) with 1 equiv of diphenylacetylene gave the trinuclear complex μ3-η1:η2:η5-(C5H4N)(C9H5)(PhC═CPh)}Ru3(CO)7 (2) via the insertion of an alkyne into the Ru−C(η1) bond of 1. Complex 2 could be transformed into the dinuclear and trinuclear complexes μ2-η1:η5-(C5H4N)(C9H5)(PhC═CPh)}Ru2(CO)2(μ2-η2:η4-CPh═CPhCPh═CPh)
