   Sammanfattning : X-ray diffraction methods have been used to study the crystal structure of different compounds, both organic and inorganic. The inorganic compounds were all synthesized by solid state reactions. A new compound, Re4As6S3, was synthesized and its structure was solved by Rietveld methods. LÄS MER
