These complexes are derived from a common, structurally characterized, Ir(III) intermediate complex [Ir(dtbbpy)(ppy)Cl2] (1), from treatment of IrCl3\u00b73H2O with equal amount of the diimine (NN\u0302) and precursor of the cyclometalated (C^N) ligands in a form of 1-pot reaction. Treatment of 1 with various functional pyrazoles afforded [Ir(dtbbpy)(ppy)(pz)Cl] (2), [Ir(dtbbpy)(ppy)(bipz)] (3), and [Ir(dtbbpy)(ppy)(mepz)] (4), which display intense room-temperature emission with \u03bbmax spanning 532-593 nm in both fluid and solid states. The Ir(III) complexes, 3 and 4, showcase rare examples of 3 distinctive chelates (i.e., neutral, anionic, and dianionic) assembled around the central Ir(III) cation. Hybrid d. functional theory (DFT; B3LYP) electronic structure calculations on 1-4 reveal the LUMO to be \u03c0*(bpy) in character for all complexes and HOMO offering d(Ir)-\u03c0(phenyl) character for 1, 2, and 4 and \u03c0(bipz) character for 3. The different HOMO composition of 3 and 4 is also predicted by calculations using pure DFT (BLYP) and wave function (MP2) methods. From time-dependent DFT calculations, the emissive processes are dominated by the Ph group-to-bipyridine, ligand(ppy)-to-ligand(bpy) charge transfer admixed with metal-to-ligand transition for all Ir(III) complexes. Organic light emitting diodes were successfully fabricated. A double emitting layer design was adopted in the device architecture using Ir(III) metal complexes 3 and 4, attaining peak external quantum efficiencies, luminance efficiencies, and power efficiencies of 18.1% (59.0 cd\/A and 38.6 lm\/W) and 16.6% (53.3 cd\/A and 33.5 lm\/W), resp.
