Usage

Chemical Properties

Stannic Fluoride or tin(iv) fluoride, is an inorganic tin fluoride compound, and generally a off-white powder. It is hygroscopic and has a melting point of 700 C or higher, well above the melting points of other tin(iv) halides.

Uses

Different sources of media describe the Uses of 7783-62-2 differently. You can refer to the following data:
1. Friedel-Crafts catalyst.
2. It is used as Friedel-Crafts catalyst.

Preparation

Stannic fluoride can be prepared from the reaction of fluorine, chlorine trifluoride, or bromine trifluoride with tin(II) or tin(IV) compounds. It acts as a Lewis acid to form many complexes. It is used in the manufacture of glasses.

Reactions

Stannic fluoride combines with ammonia and other bases, and also with alkali and other fluorides to form stannifluorides of the type M2SnF6. Stannic fluoride forms with ammonia at 43° C. the white solid SnF4.NH3, which can be heated to 400° C. with loss of very little ammonia; the compound SnF4.2NH3 is formed when stannic fluoride and ammonia are heated in a sealed tube at 120°-130° C. Both compounds dissolve in water, but their solutions gradually decompose. Aniline, pyridine, and quinoline also form additive compounds with stannic fluoride.

Polymorphism of the mixed tin fluoride Sn2F6

The mixed tin fluoride SnIISnIVF6 undergoes two phase transitions which have been unambiguously characterized by X-ray diffraction and micro-DTA. They occur at 385 ± 15 K and 470 ± 15 K. Evidence of the α ? β transition has also been given from a Mossbauer resonance investigation carried out over the temperature range 77 6-type.

Structural investigation and 119Sn Mossbauer study of graphite/SnF4 intercalation compound

The intercalation of tin tetrafluoride into graphite has been carried out in fluorinated anhydrous HF. For long reaction times, a stage-2 compound has been obtained with an identity period of 11.53 angstrom. The structural characteristics of the intercala

The BaF2-SnF4 System

The BaF2-SnF4 system is studied up to 55 mol % SnF4 by DTA and X-ray powder diffraction. The compound BaSnF6, which crystallizes congruently at 1120°C and undergoes phase transformations at 755 and 850°C, forms in the system. Another compound, hypothetically, Ba3SnF10, is formed peritectically at 900±5°C. The eutectic coordinates are 810±5°C, 35.5±2 mol % SnF4.

Synthesis, solution and magic angle spinning tin-119 nuclear magnetic resonance studies and crystal structures of dithioether complexes of tin(IV) halides

The compounds SnX4 reacted with 1 molar equivalent of dithioether, L-L, in dry CHCl3 solution to give the six-co-ordinate species [SnX4(L-L)] [X = Cl, L-L = MeS(CH2)nSMe, o-C6H4(SMe)2 or PhS(CH2)nSPh (n = 2 or 3); X = Br, L-L = MeS(CH2)nSMe or o-C6H4(SMe)2] in high yield as white or pale yellow powdered solids. Using SnBr4 and PhS(CH2)nSPh or SnI4 with MeS(CH2)nSMe did not produce isolable products, although solution 119Sn-{1H} NMR spectroscopy provided evidence for their existence at low temperatures. X-Ray structural studies on [SnCl4{MeS(CH2)2SMe}], [SnCl4{MeS(CH2)3SMe}], [SnCl4{o-C6H4(SMe)2}], [SnCl4{PhS(CH2)3SPh}] and [SnBr4{MeS(CH2)3SMe}] confirmed an S2X4 donor set with the dithioether acting as a bidentate chelate. Variable-temperature solution 1H and 119Sn-{1H} NMR spectroscopic studies showed that the complexes are extremely labile and ligand dissociation and pyramidal inversion are fast except at low temperatures. Magic angle spinning 119Sn NMR data for [SnCl4(L-L)] are reported. The crystal structure of cis-[SnI4{MeS(O)(CH2)3SMe}2], obtained as a decomposition product from the SnI4-MeS(CH2)3SMe reaction, shows monodentate sulfoxide (O) co-ordination.
