An exclusively organometallic {FeNO}(7) complex with tetracarbene ligation and a linear FeNO unit.

Abstract

The iron(II) complex 1 of a macrocyclic tetracarbene binds NO to form a low-spin (S = (1)/2) {FeNO}(7) complex (2) with a linear FeNO unit and a short Fe-NO bond. IR, electron paramagnetic resonance, and Mössbauer spectroscopies as well as density functional theory calculations suggest some Fe(I)NO(+) character and reveal that the singly occupied molecular… (More)
