, p. 815 - 820 (1990)
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.

, p. 79 - 87 (1990)
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
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.

, p. 826 - 827 (2008/10/08)
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.
