Abstract


Iridium (III) 1,3-bis(aryl)triazenide complexes [Cp?IrCl(ArNNNAr?)] (Cp? = C5Me5, Ar = Ar? = C6H5, 1; Ar = Ar? = o-CF3-C6H4, 2; Ar = Ar? = o-HOCH2-C6H4, 3; Ar = o-HOCH2-C6H4, Ar? = p-CH3-C6H4, 4) have been obtained by reaction of iridium dimer [Cp?IrCl2]2 with the corresponding triazenes in the presence of NEt3 in CH3CN. The iridium complexes 1?4 were characterized by IR, ESI-MS and NMR spectroscopy. In all of the complexes, the triazenes are coordinated to iridium (III) as monoanionic bidentate N,N?-donor ligands. Compounds 1?4 are the first examples studied by single crystal X-ray diffraction of mononuclear bis(aryl)triazenide iridium complexes, where the N-N-N fragment effectively chelates the Ir (III) central atom.
