“What do you see?” “I see a corrole radical!” An attempt to prepare sterically protected tungsten corroles led unexpectedly to the first free‐base corrole radical. In their Communication on page 8213 ff., M. Bröring and co‐workers report an air‐stable and easy‐to‐handle open‐shell 17π (4 n +1) porphyrinoid with a SOMO that resembles the symmetry of a Rorschach picture. The observed loss of one inner hydrogen atom results in an effectively planar molecular structure and the ability to bind divalent metal ions, such as Zn 2+ .
