X-ray Crystallography Laboratory

The X-ray Crystallography Laboratory of the Department of Chemistry and Biochemistry 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 facility also serves as an ancillary graduate research laboratory for selected graduate students pursuing studies in inorganic chemistry leading to a doctorate degree.

Currently, structural studies are performed on a APEX Bruker-AXS CCD X-ray diffractometer equipped with an monocap collimator. Data are collected typically at 120K. Structures are solved with SHELXTL software. Typical turn-around times under average conditions, from start of data-collection to completely refined structure, range from a few hours to a day.

Completed structures can be accessed through the web. To register for the secure web server, please send an email message with an account name and password. The Tirith Webfileserver page is compatible with latest versions of Internet Explorer, Safari and Netscape.
