New coordination polymers with 2D network structures with fluorine directly coordinated to the metal ion were prepared both via mechanochemical synthesis and fluorolytic sol–gel synthesis. Depending on the synthesis route, the samples show different particle sizes, according to SEM imaging. The crystal structures of barium acetate fluoride, strontium acetate fluoride, and lead acetate fluoride (BaF(CH₃COO), SrF(CH₃COO) and PbF(CH₃COO)) were solved from X-ray powder diffraction data. The structure solution is backed by the results from ¹⁹F MAS NMR, FT IR data, and thermal analysis. The calculated chemical shifts of the ¹⁹F MAS NMR spectra coincide well with the measured ones. It turns out that the grinding conditions have a remarkable influence on the mechanochemical synthesis and its products. Our systematic study also indicates a strong influence of the atomic radii of Ca, Sr, Ba, and Pb on the success of the syntheses.

具有直接的氟金属键的新型二维层状结构：MF（CH3COO）（M：Sr，Ba，Pb）

通过机械化学合成和氟化溶胶-凝胶合成，制备了具有2D网络结构且氟与金属离子直接配位的新型配位聚合物。根据合成路线，根据SEM成像，样品显示出不同的粒径。由X射线粉末衍射数据解析了乙酸钡氟化物，乙酸锶锶和乙酸铅氟化物（BaF（CH ₃ COO），SrF（CH ₃ COO）和PbF（CH ₃ COO））的晶体结构。¹⁹ F MAS NMR，FT IR数据和热分析的结果为结构解决方案提供了支持。计算出的^19的化学位移F MAS NMR光谱与测得的光谱非常吻合。结果表明，研磨条件对机械化学合成及其产物具有显着影响。我们的系统研究还表明，Ca，Sr，Ba和Pb的原子半径对合成成功有很大影响。
