    • Attempts to precipitate 2 were not successful, due to what appeared to be substitution of the COE ligands by the excess acetontrile present during workup. Unfortunately, weakly coordinating solvents (such as chloroform, dichloromethane, nitromethane, and benzene) reacted with complex 1 and excluded the use of stoichiometric amounts of acetonitrile for the synthesis of complex 2.

    • 6 solution), and data from these crystals were measured. The symmetry of the crystals (I4/m or R3̄) and the location of the Ir on special positions meant that the structure of 6 could not be refined satisfactorily (cf. ref 6c); however, the absence of coordinated solvent molecules could be clearly seen.
