X-Ray Facility

The X-ray facility in 165 Physical Sciences Building serves to collect data on small molecule, single crystals. The laboratory houses a Bruker APEX-II diffractometer running a molybdenum sealed-tube source. Primarily the service is provided for the Department of Chemistry, however, any small molecule (typically up to 2 kDa) can be analyzed. Funding for the instrumentation was provided for by the National Science Foundation.

Data are routinely collected at cryogenic temperatures. Typical sample sizes range from 0.1 to 0.3 mm, though advice from the resident crystallographer is recommended prior to submitting samples. The laboratory serves to further complement the range of analytical techniques already offered by the department (NMR and Mass Spectrometry) aiding researchers in further understanding the wide variety of compounds discoveed or synthesized.

The laboratory provides the following services:

• Sample examination and evaluation (optical and diffraction)
• Data collection and reduction
• Structure solution and refinement
• Crystallographic database searches
  [Cambridge Crystal Structure Database (CSD) and Inorganic Crystal Structure Database (ICSD)]

Instrumentation

Bruker APEX-II diffractometer, with a three-circle D8 goniometer and an APEX-II CCD detector. The APEX-II detector is a state-of-the-art high-speed readout area detector, coupled with the fixed-chi three-circle D8-goniometer allows for rapid and accurate data collection.

Olympus SZX-16 Trinocular stereo-zoom microscope outfitted with polarizing lenses. The high magnification of the SZX-16, coupled with the polarizing lens system allows for rigorous optical examination of samples.

Rigaku Mini-Flex desktop powder diffractometer. This instrument is operated in conjunction with the Oliver research group.
