The bis(acetylacetonato)oxovanadium(IV) (VO(acac)/sub 2/) complex and its adducts with methanol and substituted pyridines in frozen solution have been studied by ENDOR (electron nuclear double resonance). The measured ligand hyperfine splitting and quadrupole coupling components give a detailed insight into the structure of the complexes. The experimental data allow us to discriminate between possible binding sites of the sixth ligand. Whereas methanol evidently binds to the vacant axial position, either cis or trans isomers may be formed with substituted pyridines. Our results are compared with those of previous infrared studies. 5 figures, 3 tables.
