| Abstract: | A series of mixed-ligand complexes of tris(acetylacetonato) iridium(III) with N-heterocyclic ligands, namely bis(acac-O,O′)(acac-C3)Ir(L)], where acac = acetyacetonato; L = 2-picoline (1), 3-picoline (2), 4-picoline (3), have been synthesized via the reaction
of bis(acac-O,O′) (acac-C3)Ir(H2O)] with the corresponding ligand, respectively. Molecular structures of all complexes were determined by using single-crystal
X-ray diffraction. The results reveal that these complexes have slightly distorted octahedral coordination geometries. |
