A series of novel biscyclometalated iridium (III) complexes with an ancillary disulfonated bathophenanthroline (DSBP 2‐ ) ligand, Ir( L ) 2 DSBPNa, L = 2‐phenylpyridine (ppy), 2,4‐difluorophenylpyridine (fppy), and 1‐phenylisoquinoline (piq) were found to have two isomeric forms. The chemical structures of the isomers were determined by the one‐ and two‐dimensional 1 H and 13 C NMR studies. The isomeric state was proved to have originated from the disulfonate‐related regio‐isomer of the DSBP 2‐ ligand. Copyright © 2011 John Wiley & Sons, Ltd.
