Free-base corroles have long been known to be acidic, readily undergoing
deprotonation by mild bases and in polar solvents. The conjugate base, however, has not
been structurally characterized until now. Presented here is a first crystal structure of a freebase corrole anion, derived from tris(p-cyanophenyl)corrole, as the tetrabuylammonium salt.
The low-temperature (100 K) structure reveals ...
