The synthesis and characterization of a new phthalocyanine (Pc) Mn-nitride complex, ( OE Pc)MnN (2; OE Pc = 1,4,8,11,15,18,22,25-octaethoxy-Pc), as well as its stable, readily accessible oxidized (2 + and 2 2+ ) and reduced (2 - , 2 2- ) congeners is reported. This unique isostructural series displays switchable aromatic character spanning the aromatic (2), nonaromatic (2 2+ ), and antiaromatic (2 2- ) triad, in addition to the open-shell radical states (2 + , 2 - ). All complexes were structurally characterized and displayed significant structural distortions at the redox extrema (2 2+ , 2 2- ) consistent with proposed [16 or 18]annulene π ring circuit models. Spectroscopic and computational studies further support these models. This isolated, fully characterized, isostructural series spanning five redox states (2 2+ , 2 + , 2, 2 - , 2 2- ) is unique in both the Pc and related macrocyclic (ex. porphyrinoids) literature and may offer direct insight into structural-electronic correlations driven by switchable aromaticity.
