Abstract
The reaction of 1,3-propanedithiol with [Ru 3(CO) 10(μ-dppe)] ( 2) at 66°C afforded the thiolate complexes [(μ-H)Ru 3(CO) 8{μ-S(CH 2) 3SH}(μ-dppe)] ( 6) and [Ru 3(CO) 5{μ 2-S(CH 2) 3S} 2(η 2-dppe)] ( 7) in 25 and 23% yields respectively. Compound 6 is formed by simple oxidative addition of one of the S–H bonds of 1,3-propanedithiol while the structurally unique 7 consists of an open triruthenium cluster with four terminal and one asymmetrically bridged carbonyl groups, two doubly bridged propanedithiolate ligands and a chelating dppe ligand.
