The title compound, [Ru(2)(C(22)H(34)Si(2))(CO)(4)], contains two Ru(I) atoms linked by a bridging (η(5)-(t)BuC(5)H(2))(2)(SiMe(2))(2) ligand ((t)Bu 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 cyclo-penta-dienyl rings of the ligand is 123.13 (19)°. The four terminal carbonyl ligands are bound in a symmetrical and staggered array. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers.
标题化合物[Ru₂(C₂₂H₃₄Si₂)(CO)₄]包含两个通过桥连的(η⁵-(t)BuC₅H₂)₂(SiMe₂)₂配体连接的Ru(I)原子（(t)Bu为叔丁基，Me为甲基），Ru-Ru键长为2.8401(7) Å。配体的环戊二烯基环平面之间的二面角为123.13(19)°。四个末端羰基配体以对称且交错的排列方式键合。在晶体中，分子通过成对的C-H⋯O氢键相连，形成倒转二聚体。
