S1 (EPR spectra of 1 and 2 in MeOH soln.), S2 and S4 (1H NMR spectra of 1 in CD3CN), S3 and S5 (1H NMR spectra of 2 in CD3CN), S6 (cyclic voltammetry of 1 and 2) and Table S1 (1H NMR features of 1 and 2 in CD3CN at 302 K).

The first examples of mononuclear nitrogen/sulfur-ligated Co(II) alkoxide complexes, species of relevance to a reactive intermediate observed for Co(II)-substituted liver alcohol dehydrogenase, have been isolated and characterized by multiple methods including X-ray crystallography, EPR, paramagnetic (1)H NMR, and cyclic voltammetry.
