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.
Synthesis and reactions Dichlororuthenium tricarbonyl dimer arises by the carbonylation of a hot solution of ruthenium trichloride in methoxyethanol.
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).
