Abstract

The interaction of bis(O,O′-diethyldithiophosphato)oxovanadium(IV), VOdtp2, with pyridine bases has been studied in toluene by ESR. It has been found that the four-membered chelate structure of VOdtp2 is disrupted by pyridine bases to form the complex species identified as VOdtp2·Py and VOdtp2·Py2 by their characteristic ESR spectra. The coordination structures of the newly-formed complexes are discussed in association with the substitution equilibria involved.
