Y. Ohgo et al., Bis(tetrahydrofuran-kappa O)(meso-5,10,15,20-tetraisopropylporphy-rinato-kappa N-4)iron(III) perchlorate, ACT CRYST C, 57, 2001, pp. 233-234
The title complex, [Fe(C32H36N4)(C4H8O)(2)]ClO4, shows an S-4-ruffled porph
yrin ring, where the maximum deviation of the meso-carbon from the least-sq
uares plane of the [Fe(C20N4)] core is as high as 0.675 (9) Angstrom. This
is the highest class of deviation among S-4-ruffled iron(III) porphyrin com
plexes. The average Fe-N-p bond distance is 1.967 (12) Angstrom (N-p denote
s an N atom of the equatorial ligand).
