trans-Di-μ-carbonyl-bis{carbonyl[η5-2,3,4,5-tetramethyl-1-(2-thienyl)cyclopentadienyl]ruthenium(I)}(Ru—Ru)

The title compound, [Ru2(C13H15S)2(CO)4], is a centrosymmetric binuclear metal–carbonyl complex containing an Ru—Ru single bond [2.7511 (8) Å]. Each RuI atom is coordinated by two bridging carbonyl ligands, one terminal carbonyl ligand and one η5-cyclopentadienyl group. The complex has a trans conformation and the two cyclopentadienyl ring planes are parallel. The crystal structure involves weak C—H...O hydrogen bonds
