Iron tetraphenylporphin complex

Cobalt (II) meso-5.10,15,20-tetraphenylporphine complex [14172-90-8] M 671.7. Brown crystals from Et20 or CHCl3-MeOH (cf iron chloride complex). Recrystd by extraction (Soxhlet) with CgHg. Sol in most organic solvents except MeOH and pet ether. [UV, IR J Am Chem Soc 70 1808 7948 81 5111 7959.]... 

Iron (III) meso-5,10,15,20-tetraphenylporphine chloride complex [16456-81-8] M 704.0. Crystallise by extraction from a thimble (Soxhlet) with CHCI3. Concentrate the extract to ca lOmL and add ca 80mL of hot MeOH. Dark blue crystals separate on cooling. It can be recrystallised several times from CHCl3-MeOH. Avoid prolonged heating. It is quite soluble in organic solvents but insoluble in pet ether. [J Am Chem Soc 70 1808 1948 UV 73 4315 7957.]... 

The iron(I) anion [Fc(TPP)] (TPP = tetraphenylporphine dianion) is produced243 by the reduction of p-oxo-bis(tetraphenylporphineiron(III)) with Na/ Hg in THF. The product appears to exist in different spin states in THF solution (200-300 K) and frozen THF matrix at 77 K. A recent study, however,244 is unequivocal about the d1 Fe1 nature of the complex in the presence of pyridine.
