Fig. 4.

Molecular structure of the cation of [(OEP)Fe(NO)]OTf in the $P\stackrel{‒}{1}$ space group (with thermal ellipsoids drawn at 50%). The H atoms and the anion have been omitted for clarity. Fe1–N5 = 1.6371(15) Å, N5–O1 = 1.1473(19) Å, ∠Fe1–N5–O1 = 176.15(15)°. The related [(OEP)Fe(NO)]ClO₄ structure in the P2₁/n space group has been reported.^{22, 23}
