Single crystal diffractometer (renewal)

• Subject Area: Molecular Chemistry
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 583981905

The cooling system on the single crystal diffractometer needs to be replaced. Single crystal crystallography is one of the most important methods for structural analysis of molecules for all research groups at the Institute of Inorganic Chemistry. Due to the age and in turn, technical problems with the cooling system, it is now to be replaced, which will significantly increase the lifetime of the device. The cooling unit is essential for the structure determination, as it enables the temperature-control of the single crystals during data collection. This is usually done at 100 K in order to significantly reduce thermal ellipsoids and thus obtain data of adequate quality and to measure sensitive compounds which are not stable at room temperature. The replacement of the cooling system will ensure that ongoing and planned research projects at the Institute of Inorganic Chemistry can be continued using the essential method of single crystal structure analysis. The research projects of the participating research groups include, among other aspects, the investigation and development of tailor-made electrocatalysts as well as the synthesis and characterization of low-valent, highly reactive main-group compounds with unusual electronic structures. Single-crystal X-ray diffraction is an indispensable key technique in this context, as it enables the unambiguous structural elucidation of these compounds and the reactive intermediates arising within these studies. Moreover, it constitutes the central methodology of an established research framework in which structure, electron density and material properties are regarded as a continuous, interconnected continuum.
