Abstract: | The low‐spin iron(II) ion of bis(4‐methylpiperidine)(5,10,15,20‐tetraphenylporphyrinato)iron(II), Fe(TPP)(4‐MePip)2], where TPP is 5,10,15,20‐tetraphenylporphyrinate (C44H28N4) and 4‐MePip is 4‐methylpiperidine (C6H13N), is located at a center of inversion, and there is one molecule in the triclinic unit cell. The axial 4‐MePip ligands adopt a chair conformation and the α‐C atoms are oriented at angles of 21.2 (2) and 32.8 (2)° relative to the closest porphyrin N atoms. The equatorial Fe—NTPP distances are 1.998 (2) and 1.990 (2) Å, while the axial Fe—N distance is 2.107 (2) Å. The relatively short axial coordination distance reflects compression of the molecule along its principal axis by intermolecular non‐bonded interactions. |
