Reaction of the dipeptides H2Gly-Tyr and H2Gly-Phe with VCl3 and 1,10-phenanthroline affords the compounds [V(Gly-Tyr)(phen)]Cl·3MeOH 1 and [V(Gly-Phe)(phen)]Cl·3MeOH 2aerial oxidation of the complexes 1 and 2 gives their oxovanadium(IV) analogues [VO(Gly-Tyr)(phen)] 3 and [VO(Gly-Phe(phen)] 4, respectivelythe X-ray crystal structure of 3 is reported.
