This study presents the synthesis and characterization of novel heteroligand vanadyl(IV) complexes incorporating aminobenzoic acids (o-aminobenzoic acid and p-aminobenzoic acid) and biuret as ligands. Three new complexes were synthesized: [VO(L2)2]•SO4 (KB1), [VO(o-ABK)2•L2] (KB2), and [VO(p-ABK)2•L2] (KB3), where L2 represents biuret, o-ABK is o-aminobenzoic acid, and p-ABK is p-aminobenzoic acid. The compounds were characterized using infrared (IR) spectroscopy and electron paramagnetic resonance (EPR) spectroscopy. IR analysis confirmed the coordination of carbonyl oxygen atoms from biuret to the vanadyl center, while EPR spectroscopy provided insights into the electronic structure and coordination environment of the V4+ ion. The results indicate the formation of octahedral coordination complexes with potential polymeric structures in the case of the sulfate-containing complex. These findings contribute to the understanding of vanadyl chemistry and may have implications for catalytic and biological applications.
