Structural insights into [Co4O4(C5H5N)(4)(CH3CO2)(4)](+), a rare Co(IV)-containing cuboidal complex

• We report high-frequency (up to 219 GHz) and correspondingly high-field electron paramagnetic resonance spectra and X-ray crystal structure of [Co4O4(pyridine)(4)(acetate)(4)](+) ([Co4O4(py)(4)(OAc)(4)](+)) that serves as a structural and spectroscopic model of cobalt-oxide films that are capable of oxidizing water. These results are, in large part, consistent with those from our earlier, lower-frequency study and serve to benchmark future high-field studies on paramagnetic states of the catalyst film.
