2‐Amino‐3‐hydroxypyridinium dioxido(pyridine‐2,6‐dicarboxylato‐κ 3 O 2 , N , O 6 )vanadate(V), (C 5 H 7 N 2 O)[V(C 7 H 3 NO 4 )O 2 ] or [H(amino‐3‐OH‐py)][VO 2 (dipic)], (I), was prepared by the reaction of VCl 3 with dipicolinic acid (dipicH 2 ) 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 [VO 2 (dipic)] − complex and an H(amino‐3‐OH‐py) + counter‐cation. The V V ion is five‐coordinated by one O , 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 V 2 O 5 . Powder X‐ray diffraction (PXRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the synthesized powder.
