Chagas disease and Leishmaniasis, caused by Trypanosoma cruzi and Leishmania spp., respectively, are highly prevalent neglected tropical diseases (NTDs) that pose significant global health challenges. In our pursuit of effective vanadium-based therapeutics against these diseases, we previously developed several series of oxidovanadium(V) complexes featuring bidentate bioactive ligands and Schiff base tridentate ligands. The current study extends our previous research by incorporating in the same molecule, a tridentate bromo-substituted isonicotinyl hydrazone Schiff base ligand, BrIS, and a 8-hydroxyquinoline derivative (L), leading to the synthesis and comprehensive characterization of five new complexes, [V
