Abstract: | First‐row two‐coordinate complexes are attracting much interest. Herein, we report the high‐yield isolation of the linear two‐coordinate iron(I) complex salt [K(L)][Fe{N(SiMe3)2}2] (L=18‐crown‐6 or crypt‐222) through the reduction of either [Fe{N(SiMe3)2}2] or its three‐coordinate phosphine adduct [Fe{N(SiMe3)2}2(PCy3)]. Detailed characterization is gained through X‐ray diffraction, variable‐temperature NMR spectroscopy, and magnetic susceptibility studies. One‐ and two‐electron oxidation through reaction with I2 is further found to afford the corresponding iodo iron(II) and diiodo iron(III) complexes. |
