X-Ray Crystallography
The University of Cincinnati Richard C. Elder X-ray Crystallography Facility is located in 405 Old Chemistry and houses both single crystal and powder diffractometers. The facility supports research for the Department of Chemistry faculty and students, as well as other departments, universities, and industry.

Diffractometers:
Bruker Venture Dual-Source Photon-III single crystal diffractometer equipped with both Mo and Cu microfocus X-ray sources, Oxford Cryostream 800 liquid nitrogen low temperature device for variable temperature analyses in the 90-500K range.
Software: Apex suite for data collection, Shelx suite for structure solution/refinement.
Bruker APEX-II CCD single crystal diffractometer equipped with a TRIUMPH monochromator and Mo radiation source, Oxford Cryostream 700 liquid nitrogen low temperature device for variable temperature analyses in the 90-300K range.
Software: Apex suite for data collection, Shelx suite for structure solution/refinement.
Training: Introductory training provided through CHEM 8046, graduate-level X-ray Crystallography course.
Rigaku MiniFlex 6G Powder Diffractometer
- Cu radiation source
- HyPix detector
- Ambient temperature data collection
- Software: SmartLab Studio suite
Microscopes available for viewing and mounting crystals:
- Olympus SZX12 video stereomicroscope
- Olympus SZ51 stereomicroscope
Services Provided:
- Variable-temperature single crystal analyses for inorganic, organometallic, organic, and biologically-relevant small molecules. All data is measured at cryogenic temperatures unless requested otherwise. The instrument to be collected on is selected based on the sample’s needs and the research question to be answered
- Ambient temperature powder analyses intended for quality control of bulk samples as well as determining whether chemical or physical manipulation altered the material. Use Crystallographic Information Files (CIF) from structures determined by single crystal analyses for comparison to the powder diffractograms.
- Advice on crystal growth techniques, sensitive sample handling and manipulation
- Cambridge Crystallographic Database searching
