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.

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 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.
On the constitution of PbF4 with structure refinement of SnF4

Colourless single crystals of SnF4 have been prepared heating powder samples of SnF4 in Pt-tubes (500°C, 20 d). Single crystals of PbF4 could be synthesized by pressure fluorination of 'PbF4-x' and sublimation in autoclaves. The fluorides crystallize isosructural in space group I4/mmm with SnF4: a = 404.42(4) pm; c = 792.41(9) pm; Z = 2 and PbF4: a = 425.36(8) pm; c = 806.4(1) pm; Z = 2 (Guinier-de Wolff data, Cu-Kα1). The parameters zF2 of both fluorides were refined from four-circle diffractometer data (Siemens AED 2) with SnF4: R1 = 1.5%; 1623 Io(Hkl) and PbF4: R1 = 1.0%; 777 Io(hkl) (SHELXL-93). The structures correspond to the supposition by Hoppe and Daehne from 1962. The Madelung Part of Lattice and Molecule Energy, MAPLE and MAPME, Mean Fictive Ionic Radii, MEFIR, and Effective Coordination Numbers, ECoN, are calculated. Johann Ambrosius Barth 1996.
