Dichlororuthenium tricarbonyl dimer is an organoruthenium compound with the formula [RuCl₂(CO)₃]₂. A yellow solid, the molecule features a pair of octahedral Ru centers bridged by a pair of chloride ligands. The complex is a common starting material in ruthenium chemistry.^[1]

Synthesis and reactions

Dichlororuthenium tricarbonyl dimer arises by the carbonylation of a hot solution of ruthenium trichloride in methoxyethanol.^[2]

The complex exists in equilibrium with the polymer:

n [RuCl₂(CO)₃]₂ → [RuCl₂(CO)₂]_2n + 2 CO

It reacts with potassium hydroxide in alcohol to give triruthenium dodecacarbonyl.

Dichlororuthenium tricarbonyl dimer reacts with glycine to give tricarbonylchloroglycinatoruthenium(II).^[3]
