degrees = -109.5 J mol(-1) K(-1)). NHC 1 also displayed nucleophilic characteristics. Treatment of 1 with [Ir(COD)Cl](2) (COD = 1,5-cyclooctadiene) afforded 1-[Ir(COD)Cl], a complex with bond lengths and angles that were in accord with known NHC analogues. Treatment of 1-[Ir(COD)Cl] with CO afforded the carbonyl complex 1-[Ir(CO)(2)Cl]. IR studies of this complex revealed a Tolman Electronic Parameter
