Abstract

A complete reversal of the spin state of iron(III) is observed upon a small change to the diporphyrin bridge from ethane to ethene by keeping all other factors intact. Combined analysis using single crystal X-ray structure determination, Mössbauer, variable-temperature magnetic, 1H NMR and EPR studies has confirmed the spin states of iron(III) complexes both in solid and solution phases.
