Iron and copper complexes of tetraphenyl-m-benziporphyrin (TPmBPH)H have been prepared and structurally characterized. The iron system, (TPmBPH)FeIIBr, contains a high-spin Fe(II) center. In the solid state the complex forms dimeric units linked by weak CH···Br hydrogen bonds. The Cu complex contains a tetrameric copper cluster with a Cu2Cl42- unit bridging two [(TPmBPCl)CuII]+ fragments. The formation of (TPmBPCl)H represents an example of copper-catalyzed chlorination on the internal carbon atom of (TPmBPH)H.
