Abstract

The reaction of [Fe^II(L^•)₂][BF₄]₂ with LiTCNQF₄ results in the formation of [Fe^II(L^•)₂][TCNQF₄^•-]₂·2CH₃CN (1) (L^• is the neutral aminoxyl radical ligand 4,4-dimethyl-2,2-di(2-pyridyl)oxazolidine-N-oxide; TCNQF₄ is 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane). Single-crystal X-ray diffraction; Raman, Fourier-transform infrared (FTIR) and ultraviolet-visible spectroscopies; and electrochemical studies are all consistent with the presence of a low-spin Fe^II ion, the neutral radical form (L^•) of the ligand, and the radical anion TCNQF₄^•^-. 1 is largely diamagnetic and the electrochemistry shows five well-resolved, diffusion-controlled, reversible one-electron processes.
