Synthesis A solution of 6 mL of 1,5-cyclooctadiene in 35 mL of ethanol and 20 mL of water is added to 2.0 g of IrCl3.3H2O in a round-bottomed flask. The mixture is refluxed under nitrogen for 24 h when an orange-red product precipitates from the solution. The mixture is cooled to rt, and Di-μ-chlorobis(1,5-cyclooctadiene)diiridium(I) (Chloro(1,5-cyclooctadiene)iridium(I) dimer) is collected by filtration, washed with cold methanol, and dried in vacuo at 25 °C for 8 h.
