摘要

用19F， 1H NMR研究了一系列ZnZrF6·nH2O （n = 6,5,4,2,0）六氟锆酸盐。对获得的19fmas核磁共振信号进行了分配。根据阳离子的组成和水化程度，考虑了核磁共振谱的形状和信号的位置随结构变化的行为。所得数据与已知的氟锆酸盐核磁共振数据进行了比较。分析了记录光谱的宽谱线形状，并考虑了它们对水分子（n = 2,5）、\(\text{ZrF}_{ 6}^{2-}\)离子（n = 6）和ZnF2(H2O)4离子（n = 4）重定向运动的温度依赖关系。

Structure and 19F, 1H NMR Spectra of Zinc Hexafluorozirconate Hydrates

A series of ZnZrF₆·nH₂O (n = 6, 5, 4, 2, 0) hexafluorozirconates is studied by ¹⁹F, ¹H NMR. Assignments are made for the obtained ¹⁹F MAS NMR signals. Behavior of the shape of NMR spectra and positions of their signals upon structural changes is considered depending on the composition and hydration degree of the cation. The obtained data are compared with known NMR data for fluorozirconates. The shapes of broad lines of the recorded spectra are analyzed, and their temperature dependence as a result of reorientational motions of water molecules (n = 2, 5), \(\text{ZrF}_{ 6}^{2-}\) ions (n = 6), and ZnF₂(H₂O)₄ ions (n = 4) is considered.
