Single-Crystal X-ray Diffraction

We run two modern single-crystal X-ray-diffractometers at our institute. These machines enable us to determine the structure of even large and low-diffracting structures containing weakly coordinating anions.

Responsible for single-crystal X-ray diffraction in our group is Dr. Burkhard Butschke.

In this environment, several computer programs have been developed to facilitate the handling of large and heavily disordered structures:
