Chlorobis(cyclooctene)iridium dimer is an organoiridium compound with the formula Ir₂Cl₂(C₈H₁₄)₄, where C₈H₁₄ is cis-cyclooctene. Sometimes abbreviated Ir₂Cl₂(coe)₄, it is a yellow, air-sensitive solid that is used as a precursor to many other organoiridium compounds and catalysts.

The compound is prepared by heating an alcohol solution of sodium hexachloroiridate with cyclooctene in ethanol.^[2] The coe ligands are easily displaced by other more basic ligands, more so than the diene ligands in the related complex cyclooctadiene iridium chloride dimer.
