Abstract: The title compound, [Ru2(C22H34Si2)(CO)4], contains two RuI atoms linked by a bridging ([eta]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-H...O hydrogen bonds, forming inversion dimers.
