Heavy‐element corroles are of great interest as optical sensors, near‐IR dyes, phosphors, organic light‐emitting diodes, and anticancer compounds, but the insertion of 5d metals into corroles is difficult. In their Communication on page 14411 ff., A. Ghosh and co‐workers present the oxidative metalation of meso triarylcorroles with [Os 3 (CO) 12 ]/NaN 3 as a route to nitridoosmium(VI) corroles. These complexes exhibit distinctive domed folded macrocycles and multiple Os–nitrido stretching frequencies.
