The hexafluorosilicate with the composition (LH)₂SiF₆·H₂O (I, L = 3-hydroxymethylpyridine) was obtained by reaction of 45 % hexafluorosilicic acid with a methanol solution of L (H₂SiF₆ : L = 3: 1). The crystal structure I is stabilized by OH···O, NH···F, and OH···F H-bonds, and CH···F contacts. The symmetry of the SiF₆^2– anion is close to D_4h. The solubility of I in water was 1.63 mol. % and the degree of hydrolysis of the salt in a 1·10^–4 M aqueous solution was 91.6 %. A PASS-analysis of the spectrum of biological activity L highlighted a low probability of toxic effects.

双（3-羟甲基吡啶鎓）六氟硅酸盐一水合物作为新型潜在的抗龋剂：合成，晶体结构和药理性质

组成为（LH）₂ SiF ₆ ·H ₂ O（I，L = 3-羟甲基吡啶）的六氟硅酸盐是通过使45％六氟硅酸与L的甲醇溶液（H ₂ SiF ₆：L = 3：1）反应获得的）。晶体结构I通过OH··O，NH···F和OH··F的H键稳定化，并且CH··F接触。SiF ₆ ^2–阴离子的对称性接近D _{4 h}。I在水中的溶解度为1.63mol。％和盐的水解度为1·10 ^–4M水溶液为91.6％。对生物活性谱L的PASS分析强调了毒性作用的可能性较低。
