AI Article Synopsis
- The study focuses on synthesizing and characterizing two iridium(III) corrole compounds: 5,10,15-tris-pentafluorophenylcorrolato-iridium(III) bis-trimethylamine and its octabromo variant.
- Both compounds exhibit a nearly planar structure, with low mean deviations from the plane (0.0371 A for compound 1 and 0.0325 A for compound 2).
- The UV-vis spectra show a unique split Soret band and cyclic voltammetry indicates that while iridium(II) cannot be generated, oxidation to iridium(IV) occurs at lower potentials than typically observed in other complexes.
Article Abstract
This work reports the synthesis and full characterization of 5,10,15-tris-pentafluorophenylcorrolato-iridium(III) bis-trimethylamine 1 and its octabromo derivative 2. The corrole is planar in both cases (the mean deviation from the plane is as low as 0.0371 A for 1 and 0.0325 A for 2), the UV-vis spectra display a split Soret band with a shoulder attributable to an MLCT transition, and cyclic voltammetry reveals that the iridium(II) oxidation state cannot be accessed, while the oxidation to formal iridium(IV) complexes is achieved at much lower potentials than in other coordination environments.
