2-Amino-3-hydroxypyridinium dioxido(pyridine-2,6-dicarboxylato-κ(3)O(2),N,O(6))vanadate(V), (C5H7N2O)[V(C7H3NO4)O2] or [H(amino-3-OH-py)][VO2(dipic)], (I), was prepared by the reaction of VCl3 with 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 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 V2O5. Powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM) were used to characterize the structure and morphology of the synthesized powder.
2-氨基-3-羟基吡啶双氧（吡啶-2,6-二羧基-κ(3)O(2),N,O(6)）钒（V），(C5H7N2O)[V(C7H3NO4)O2] 或 [H(氨基-3-羟基吡啶)][VO2(吡啶-2,6-二甲酸)]，（I），通过VCl3与吡啶-2,6-二甲酸（dipicH2）和2-氨基-3-羟基吡啶（氨基-3-羟基吡啶）在水中反应制备。该化合物通过元素分析、红外光谱和X射线结构分析进行表征，由阴离子VO2(吡啶-2,6-二甲酸)络合物和H(氨基-3-羟基吡啶)(+)抗衡阳离子组成。V(V)离子由一个O,N,O'-三齿吡啶-2,6-二甲酸二价阴离子配体和两个氧化物配体五配位。在聚乙二醇存在下（I）的热分解导致形成V2O5纳米颗粒。粉末X射线衍射（PXRD）和扫描电子显微镜（SEM）用于表征合成粉末的结构和形态。
