In the chloroiron(III) complex of meso-tetrapropyl-porphyrin, [Fe(C32H36N4)
Cl], the Fe-III atom has slightly distorted square pyramidal coordination.
The porphyrin ring shows a typical S-4-ruffled structure in addition to a n
ormally observed domed core; the deviations of the meso-C and Fe atoms from
the least-squares plane of the C20N4 core are 0.366(4) (maximum) and 0.578
(1) Angstrom, respectively. The average Fe-N-p bond distance is 2.063 (4) A
ngstrom.
