Dichlororuthenium tricarbonyl dimer explained

Dichlororuthenium tricarbonyl dimer is an organoruthenium compound with the formula [RuCl<sub>2</sub>(CO)<sub>3</sub>]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 [RuCl<sub>2</sub>(CO)<sub>3</sub>]2 → [RuCl<sub>2</sub>(CO)<sub>2</sub>]2n + 2 COIt reacts with potassium hydroxide in alcohol to give triruthenium dodecacarbonyl.

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