Single crystal X-ray diffraction is a leading technique for the determination of molecular and crystal structures and for obtaining the absolute configuration of molecules. This laboratory allows researchers to do small molecule single crystal structure determinations, where the metrical details of a molecule are ascertained (such as, bond lengths, bond angles, and conformation) along with the arrangement of the molecules within the solid state. Students with crystallographic experience can collect diffraction data and/or solve and refine their own structures. Otherwise, the complete structure analysis is done by the staff crystallographer.
Equipment for single crystal work:
Nonius Kappa APEX-II Diffractometer
Instrument is equipped with a Moly sealed tube and an Apex-II CCD detector as well as an Oxford Cryosystems Cryostream for variable temperature data collection from 90-400 K.
Bruker D8 Venture Diffractometer
Dual source instrument equipped with a TRIUMPH monochromated Moly sealed tube and a Copper IµS. System features a Kappa goniometer and a Photon II detector as well as an Oxford Cryosystems Cryostream for variable temperature data collection from 90-400 K.
Equipment for powder work:
Bruker D8 Advance Diffractometer
A high resolution versatile instrument which has several different sample holders. These include a standard flat sample reflection holder, a 9-sample changer, a capillary holder, and a high temperature oven (100 C - 1200 C). Instrument is equipped with a Cu sealed tube and LYNXEYE XE-T detector. Johansson monochromator allows for data collections using only Kα1 radiation.
