(Benzene)ruthenium dichloride dimer is the organoruthenium compound with the formula [(CH)RuCl]. 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. As verified by X-ray crystallography, each Ru center is coordinated to three chloride ligands and a η-benzene. The complex can be viewed as an edge-shared bioctahedral structure.
(Benzene)ruthenium dichloride dimer reacts with Lewis bases to give monometallic adducts: [(CH)RuCl] + 2 PPh → 2 (CH)RuCl(PPh)
