Due to the sensitivity to air and moisture, all samples were prepared in sealed capillaries (Ø0.3 mm, WJM-Glas-Müller GmbH, Berlin, Germany). The data collection was carried out on an STOE Stadi P diffractometer (STOE, Darmstadt, Germany) (Monochromatic Mo Kα1 radiation, λ=0.70926 Å) equipped with a Dectris Mythen 1 K detector. For visualization and indexation, the software WinXPOW and Jana2006 were used.
