L-proline was used to prepare chiral, tridentate amino acid phenol proligands H2L1—4. These
proligands react with vanadium precursors VO(acac)2, VOSO4 ∙ 5 H2O and VO(OPr)3 in
methanol to form the corresponding oxidoalkoxidovanadium(V) complexes 1—4. The
complexes crystallize from methanol, and are octahedrally coordinated with a general
formula [VO(L1—4)(OMe)(MeOH)]. In solution, however, they adopt several different
conformations or isomeric structures depending on the solvent.
