Abstract: The title compound, [Ru₂(C₂₂H₃₄Si₂)(CO)₄], contains two Ru^I atoms linked by a bridging (⁵-^tBuC₅H₂)₂(SiMe₂)₂ ligand (^tBu is a tert-butyl and Me is a methyl group) with an Ru-Ru bond length of 2.8401 (7) Å. The dihedral angle between the planes of the cyclopentadienyl rings of the ligand is 123.13 (19)°. The four terminal carbonyl ligands are bound in a symmetrical and staggered array. In the crystal, molecules are linked via pairs of C-HO hydrogen bonds, forming inversion dimers.
