The complex of antimony(III) fluoride with glycine 2SbF3·(C2H5NO2) (I) has been synthesized and investigated by X-ray, and 19F, 1H NMR methods. The structure of I is formed by the molecular SbF3(C2H5NO2)SbF3 groups linked through Sb···F secondary bonds into polymer layers parallel to the (bc) plane. The longer Sb···F bonds (2.674–3.354 Å) and the N–H···F and C–H···F hydrogen bonds link the layers into a three-dimensional framework. The character of ionic motions in fluoride and proton sublattices upon temperature variations in the range 150–435 K has been examined, and their types and temperature ranges, within which they are realized, have been determined. It has been established that ion diffusion in both sublattices of I is observed in the temperature range 400–435 K, and the mechanisms of its emergence are proposed.

甘氨酸2SbF 3 ·(C 2 H 5 NO 2)氟化锑(III)配合物的晶体结构和离子迁移率

合成了氟化锑(III)与甘氨酸2SbF 3 ·(C 2 H 5 NO 2)(I)的配合物,并通过X射线,19 F,1 H NMR方法进行了研究。I的结构由分子SbF 3(C 2 H 5 NO 2)SbF 3形成通过Sb···F次级键连接的基团平行于(bc)平面的聚合物层。较长的Sb···F键(2.674–3.354Å)和N–H··F和C–H··F氢键将这些层连接成三维框架。考察了氟化物和质子亚晶格在150–435 K范围内的温度变化时离子运动的特征,并确定了它们的类型和温度范围。已经确定在温度范围为400–435 K的情况下,在I的两个子晶格中都观察到了离子扩散,并提出了其出现的机理。
