Electronic Structure and Transformation of Dinitrosyl Iron Complexes (DNICs) Regulated by Redox Non-Innocent Imino-Substituted Phenoxide Ligand

Abstract

The coupled NO-vibrational peaks [IR ν NO 1775 s, 1716 vs, 1668 vs cm −1 (THF)] between two adjacent [Fe(NO) 2 ] groups implicate the electron delocalization nature of the singly O-phenoxide-bridged dinuclear dinitrosyliron complex (DNIC) [Fe(NO) 2 (μ-ON 2 Me )Fe(NO) 2 ] (1). Electronic interplay between [Fe(NO) 2 ] units and [ON 2
