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.
