Preferred Definitions:    L-b = 1,3-diketonate derived from 1,3-diketone, 3-ketonate derived from 3-ketoester, carboxylate derived by aminocarbonic acid, salicyliminate derived from salicylimine and borate nitrogen containing heterocyclic group;    D1 = N;    Y1 = CR2, C(=O), C(=CR2), O, S, NR, PR, P(=O)R or BR;    n = 2 or 3; and    m, o = 0.    SPECIFIC COMPOUNDS - 159 Compounds (I) are specifically disclosed e.g. fac-tris(4-azafluorenyl-kappaN, kappaC)iridium (III) of formula (Ia).    EXAMPLE - A suspension of sodium(bis(acetylacetonato)-dichloro)-iridate(III) (484 mg) and 4-azafluorene (1 g) in ethylene glycol (5 ml) was heated at 180degreesC for 150 hours. The reaction mixture was cooled to 60degreesC followed by the addition of aqueous hydrochloric acid (25 ml) and ethanol (25 ml) to give fac-tris(4-azafluorenyl-kappaN, kappaC)iridium (III) (243 mg).
