The study describes the tetragonal crystal structure of the non-centrosymmetric lanthanoid(III)-oxidoantimonate(III)-chlorides LnSb2O4Cl (Ln = Gd-Lu). The compounds consist of anionic layers in which the bismuth atom is present as a trivalent cation. The lanthanoid forms a trivalent cation and the halogen is singly negatively charged. The compounds are held together by layers of halide anions. The study also describes the product synthesis of the lanthanoid(III)-oxidoantimonate(III)-chlorides, with terbium oxide (Tb2O3) being produced from terbium (Tb) and terbium tetroxide (Tb4O7). The reactions take place in evacuated quartz glass ampoules. The crystal structure of the compounds is analyzed using single crystal X-ray diffraction. The compounds have similar structures and angles. [Extracted from the article]

The article is a dedication for the 60th birthday of Christian Näther, a German chemist. Näther was born in Frankfurt am Main in 1962 and completed an apprenticeship as a chemical laboratory technician. He studied chemistry at Johann Wolfgang Goethe University in Frankfurt and obtained his doctorate there in 1994. Since 1997, he has been working at Christian-Albrechts-University in Kiel, where he expanded his knowledge in single crystal structure analysis. Näther has also familiarized himself with magnetochemistry and developed a synthetic approach to coordination polymers. He is a respected collaborator and co-author of over 800 scientific publications. In addition to his research activities, he is also a dedicated teacher and has been recognized for his scientific work. [Extracted from the article]

An overview of commonly available, state-of-the-art diffraction techniques for university research is presented based on some chemical case studies. Examples from the Fribourg crystallography service are presented, aimed at scientists who would like to learn about the principal possibilities that X-ray powder and single-crystal diffraction can offer, how these methods can serve to determine the structure of a given material, and how they can help to identify polymorphs, surface coatings and enantiomers.
