SbF5, AsF5, and BF3 all form 1 : 1 adducts with SnF2, and SbF5 also forms a 1 : 2 adduct, SnF2,2SbF5. Tin(II) fluoride also reacts with fluorosulphuric acid to give Sn(SO3F)2. On the basis of their vibrational and 119Sn Mössbauer spectra, the 1 : 1 adducts are formulated as salts of the fluorine-bridged (Sn–F)nn+ cation with the anion SbF6–, AsF6–, or BF4–. The spectral results show that there is appreciable
的SBF 5,ASF 5,和BF 3的所有形式1:1个加合物的SnF 2,和的SBF 5还形成1:2的加合物,的SnF 2,2SBF 5。
氟化
锡(II)也与
氟硫酸反应生成Sn(SO 3 F)2。根据其振动光谱和119 SnMösSBauer光谱,将1:1的加合物配制成
氟桥联(Sn–F)n n +阳离子与阴离子SBF 6 –,AsF 6 –或BF 4 –的盐。。光谱结果表明,存在的Sn(SO可观的共价阳离子-阴离子相互作用3 F)2,并且还在的SnF 2,2SBF 5这是最好视为
锡(SBF 6)2。后者的化合物据报道具有最高的119 SnMsSBöauer异构体位移。
