(Benzene)ruthenium dichloride dimer is the organoruthenium compound with the formula [(C₆H₆)RuCl₂]₂. This red-coloured, diamagnetic solid is a reagent in organometallic chemistry and homogeneous catalysis.

Preparation, structure, and reactions

The dimer is prepared by the reaction of cyclohexadienes with hydrated ruthenium trichloride. ^[1] As verified by X-ray crystallography, each Ru center is coordinated to three chloride ligands and a η ⁶-benzene. ^[2] The complex can be viewed as an edge-shared bioctahedral structure.

(Benzene)ruthenium dichloride dimer reacts with Lewis bases to give monometallic adducts:

[(C₆H₆)RuCl₂]₂ + 2 PPh₃ → 2 (C₆H₆)RuCl₂(PPh₃)
