Pyridine aldoxime ligation to iridium(III) centre: An innocent ancillary ligand in a series of organometallic complexes

•Novel Ir(III) complexes were prepared by employing pyridine-2-aldoxime with three different cyclometallating ligands.•All Complexes had usual coordination of cyclometallating ligands unlike an ortho CH bond activation by pyridine-2-aldoxime in an earlier report.•Pyridine-2-aldoxime behaved as an innocent ligand in all three complexes.•A water dimer formed in the crystal lattice of a complex.
