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

The dimer is prepared by the reaction of the phellandrene with hydrated ruthenium trichloride. In solution, [(cymene)RuCl2]2 exchanges with other arenes, releasing free p-cymene.

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

Such monomers adopt pseudo-octahedral piano-stool structures.

Treatment of [(cymene)RuCl2]2 with the chelating ligand TsDPENH. The product (cymene)Ru(TsDPEN-H) is a catalyst for asymmetric transfer hydrogenation.

[(cymene)RuCl2]2 is also used to prepare catalysts (by monomerization with dppf) used in borrowing hydrogen catalysis, a catalytic reaction that is based on the activation of alcohols towards nucleophilic attack.
