对于芳香胺及其氮氧化物与氢离子形成的化合物[H(Phen)_2]ClO_4、[H(napy)_2]ClO_4、[H(pyo)_2]ClO_4(Phen:邻菲啰啉,napy:1,8-萘啶,pyo:吡啶氮氧化物)等的研究,以往的工作主要限于测定稳定常数和光谱,而对它们的结构尚未进行研究。属于芳香胺氮氧化物类的1,8-萘啶氮氧化物(简称napyo)与金属离子具有很好的配位作用。为了研究napyo同氢离子的作用情况,我们在甲醇介质中制备出未见报道的[H(napyo)_2]ClO_4单晶,研究了它的晶体结构和电子结构。
For the compounds [H (Phen) _2] ClO_4, [H (napy) _2] ClO_4 and [H (pyo) _2] ClO_4 formed by aromatic amines and their nitrogen oxides and hydrogen ions, 1,8-naphthyridine, pyo: pyridine nitrogen oxides) and other studies, the previous work mainly limited to the determination of the stability constants and spectra, and their structure has not been studied. 1,8-naphthyridine nitrogen oxides (napyo) belonging to the class of aromatic amine nitroxides have good coordination with metal ions. In order to study the effect of napyo on hydrogen ion, we have prepared an unidentified [H (napyo) _2] ClO_4 single crystal in methanol and studied its crystal structure and electronic structure.
