thioamide units. The differences of the IR spectra before and after protonation indicate that the major binding mode of CN-xylyl to iron(II) changes from π-back donation from metal to isocyanide to σ-donation from isocyanide to iron(II). This indicates that the σ-donor ability of the thioamide sulfur atom is tuned by deprotonation/protonation of thioamide.
