X-ray Crystallographic Facility

Dr. Christopher Incarvito Director 203 432 3930

The X-Ray Crystallographic Facility of the Department of Chemistry conducts characterizations by X-Ray diffraction of small-molecule organic or inorganic single crystals submitted primarily by the Department. As an extension service, the facility also accepts sample submissions from other departments of the University, and from local, national, and international collaborators of academe and industry. The laboratory is a part of the Departmental Chemical Instrumentation Center that is a comprehensive facility containing a vast array of medium and high frequency NMR spectrometers, GC/MS, LC/MS, and MALDI-TOF/MS. In addition, the center also maintains a collection of instruments for optical spectroscopy that includes FT-IR, Raman, CD, UV-VIS, fluorescence, polarimetric and atomic adsorption instruments.

The facility houses a Bruker-Nonius KappaCCD area detector X-ray diffractometer equipped with a fully integrated 4-circle goniometer and an FR590 3 kW sealed tube generator. Data collections are performed routinely at low temperatures (-50 to -150 º C) with sealed, fine-focus molybdenum-target tubes operated at 55 kV and 32 mA. We are capable of handling samples that are sensitive to air, moisture, and/or temperature and we welcome all challenges. Additional equipment includes an Olympus SZ Stereo Microscope with polarizing attachments, access to the Cambridge Structural Database©, and several Linux and Windows based PCs.
