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 η6-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)
