Simple synthesis of a six-co-ordinated high-spin iron(III) porphyrin; X-ray structure and magnetic properties of bis(ethanol)tetraphenylporphinatoiron(III) tetrafluoroborate

Abstract
Reaction of the µ-oxo-dimer of iron(III) tetraphenylporphyrin with aqueous tetrafluoroboric acid in the presence of ethanol gives bis(ethanol)tetraphenylporphinatoiron(III) tetrafluoroborate, the structure of which has been determined by X-ray crystallography; this complex is a rare example of a structurally characterized six-co-ordinated iron(III) porphyrin with an unambiguous S= 5/2 ground state.
