Abstract
2-Amino-3-hydroxypyridinium dioxido(pyridine-2,6-dicarboxylato-κ3O2,N,O6)vanadate(V), (C5H7N2O)[V(C7H3NO4)O2] or [H(amino-3-OH-py)][VO2(dipic)], (I), was prepared by the reaction of VCl3with dipicolinic acid (dipicH2) and 2-amino-3-hydroxypyridine (amino-3-OH-py) in water. The compound was characterized by elemental analysis, IR spectroscopy and X-ray structure analysis, and consists of an anionic [VO2(dipic)]−complex and an H(amino-3-OH-py)+counter-cation. The VVion is five-coordinated by oneO,N,O′-tridentate dipic dianionic ligand and by two oxide ligands. Thermal decomposition of (I) in the presence of polyethylene glycol led to the formation of nanoparticles of V2O5. Powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the synthesized powder.
