Variable temperature (100—295 K) single-crystal X-ray diffraction study of the α -polymorph of glycylglycine and a glycylglycine hydrate
The crystal structures of the α-polymorph of glycylglycine (glygly) and of its hydrate (glygly × 1.5 H2O) were refined by single-crystal X-ray diffraction at 100, 150, 220, and 295 K (glygly) and at 100, 200, 295 K (glygly × 1.5 H2O)...

02/2006 | Zeitschrift für Kristallographie, Oldenbourg WissenschaftsverlagEffect of hydrostatic pressure up to 6 GPa on the crystal structures of ammonium and sodium hexafluorosilicates, (NH4)2SiF6 and Na2SiF6; a phase transition in (NH4)2SiF6
An in situ X-ray powder diffraction study has shown the cubic modification of (NH4)2SiF6 (cryptohalite, space group Fm¯3m) at 0.2–0.3 GPa to transform irreversibly into the trigonal bararite, space group P¯3m1...
