Single crystal X-ray diffractometer with Mo and Ag sources

• Subject Area: Molecular Chemistry
• Term: Funded in 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422037655

Single-crystal X-ray diffraction analysis is used to elucidate the three-dimensional structure of molecules. Many research topics at the Institute of Organic and Biomolecular Chemistry deal with molecules that contain heavy elements or that produce only very poorly scattering crystals. The former include, in particular, the Ru catalysts used in the Ackermann group, as well as the Au, Pt, and Ir complexes studied in the Alcarazo group, and other compounds which contain two or more heavy metals. The absorption problems occurring in this type of measurements may be treated for the first time at the Institute of Organic and Biomolecular Chemistry by the Ag radiation of the device applied for. On the other hand, the Hansmann group often produces weakly scattering crystals of organic radicals, whose accurate structure determination is of central interest. The other groups of the IOBC also have a need for high-resolution structure determinations in the context of research questions. For such demanding measurements planned, the requested device is equipped with a photon-counting detector of the latest generation, as it has not yet been available at the faculty, and should decisively improve the possibilities for structure determination in our institute.
