Abstract

A detailed analysis of the previously obtained EPR spectra of the V(II)–pyrocatechol complex active in the reduction reaction of molecular nitrogen was performed. On the basis of structural data for related systems, a previous interpretation based on the complete disappearance of exchange interactions was revised. The hyperfine structure of the EPR spectrum of the test complex was explained as a consequence of strong exchange interactions, which effectively withdraw a portion of V atoms. A conclusion on the tetranuclear character of the active complex was made.
