Figure 1

a) Molecular structure of [Fe(CO)5].+[Al(ORF)4]− (1) (P212121, R 1=5.4 %, wR 2=9.0 %); thermal ellipsoids set at 50 % probability. b) Experimental ZnSe‐ATR FT‐IR spectrum of solid 1. c) Experimental and simulated Q‐band (34 GHz), continuous‐wave EPR spectra of solid 1 at 100 K, a potential impurity is marked by an asterisk. d) The carbonyl region of experimental ZnSe‐ATR FT‐IR spectrum of solid 1 (black), 1 in 4FB (gray), solid 2 (green) and calculated (@BP86‐(D3BJ)/def2‐TZVPP) 13C IR spectrum of the superposition of all possible isotopomers weighed by their natural abundance (blue). Double or more 13C substitution were neglected.
