bis-cyclometalated iridium(III) complexes with phenanthroline-type α,α′-diimin ligands bearing bulky alkyl groups in the neighbourhood of the N-donor atoms. These ligands implicate a distorted octahedral coordination geometry that in turn destabilized the Ir–NN^N bonds. The new iridium(III) complexes are not luminescent. All compounds show an electrochemically irreversible anodic peak between 1.15 and 1
