本文研究了SnF_2-MF_2（M = Mg，Ca，Sr，Ba，Pb）体系的水溶液和熔融溶液，并描述了晶体Sr（SnF_3）_2，Ba（SnF_3）_2，PbFSnF_3，Sr_2Sn_2NO_3F_7，2H_2O和Pb_2SnNO_3F_5，2H_2O的制备。这些材料的红外和119 Sn穆斯堡尔谱与所有材料中存在的SnF 3-离子一致。有没有证据表明锡硝酸盐键合在含硝酸盐的阶段，但有一个增加的Sn-F键的离子特性相比，金属（II）三氟锡酸盐（II）。没有衍生物的Sn_2F_5-离子从水溶液中分离出来，但在熔融体系的相图中发现了这些化合物的特征，并制备了固体配合物Sr（Sn_2F_5）_2和Ba（Sn_2F_5）_2。
The aqueous and molten SnF2–MF2(M = Mg, Ca, Sr, Ba, and Pb) systems have been studied and the preparation of the crystalline trifluorostannates(II) Sr(SnF3)2, Ba(SnF3)2, PbFSnF3, Sr2Sn2NO3F7,2H2O, and Pb2SnNO3F5,2H2O described. The infrared and 119Sn Mossbauer spectra of these materials are consistent with the presence of the SnF3– ion in all of them. There is no evidence for tin–nitrate bonding in the nitrate-containing phases but there is an increase in the ionic character of the Sn–F bonds compared with the metal(II) trifluorostannates(II). No derivative of the Sn2F5– ion was isolated from aqueous solutions but features attributable to such compounds were found in the phase diagrams of the molten systems, and the solid complexes Sr(Sn2F5)2 and Ba(Sn2F5)2 were prepared.
