mu-Oxo-bis[(2,3,12,13-tetrabromo-5,10,15, 20-tetraphenylporphyrinato)iron(III)] bis(dichloromethane) solvate.

The precise structure of the title compound, [Fe(2)O(C(44)H(24)Br(4)N(4))(2)].2CH(2)Cl(2), is reported. The Fe-N distances are non-equivalent in pairs because of the asymmetric peripheral substitution; the values are 2.098 A to the brominated rings and 2.041 A to the other two rings. The Fe-O bond distance is 1.7583 (4) A. The molecule has required twofold symmetry so that there is one unique porphyrin macrocycle and one Fe-O bond length in contrast to a previous report on the same species.
