Summary
A vanadium(IV) complex [VO(sal-L-Trp)(H2O)] 1 (sal-L-Trp = N-salicylidene-L-tryptophanate) has been isolated from solutions containing oxovanadium(IV), L-tryptophan and salicylaldehyde. From solutions also containing quinolin-8-ol (Hhquin) a similar oxovanadium(Iv) complex VO(sal-L-Trp). Hhquin . 2H(2)O 2 was isolated. From solutions of 1 in water-pyridine, orange-brown crystals of [Hpy(+)](4)[C14H13N2+](2)[V10O286-] 3 were isolated and characterized by X-ray diffraction. The mechanism proposed for this reaction involves the attack of a pyridine molecule at the beta-carbon atom of the tryptophan residue in 1.
