Abstract

A series of isocyanide complexes, [Fe(Porphyrinoid)( ^tBuNC) ₂] ⁺, were synthesized and examined for their physicochemical properties. The molecular structure of the bis( ^tBuNC) adduct of the iron(iii) porphycene (1) and corrphycene (2) adopting the (d _xy) ²(d _xz, d _yz) ³ ground state were determined for the first time. Furthermore, 1 and 2 showed unusual crossover phenomena between different electron configurations, (d _xy) ²(d _xz, d _yz) ³ ground state and (d _xz, d _yz) ⁴(d _xy) ¹ ground state, by the addition of the external stimuli.
