摘要
The crystal structure of hydrated iron(III) 5,10,15,20-tetra(N-methyl-4-pyridinio)porphyrin pentachloride has been determined. It crystallises as high-spin six-co-ordinated diaqua monomers (molecular symmetry 1BAR). The iron atom lies in the plane of a flat porphyrin ring [Fe-N(porphyrin), 2.042(6) and 2.038(7) angstrom]. The axial water ligands [Fe-H2O 2.086(5) angstrom] are hydrogen-bonded to chloride ions and water molecules in a network of negative charges that interlace between the positively charged iron(III) porphyrins.
