X-ray diffraction data can be used to determine the locations of all atoms within the unit cell of a crystal, and in this way the atom types, connectivity, and distances and angles within the constituent molecules can be established.
X-ray diffraction data sets are collected on a Nonius Kappa-CCD area-detector diffractometer equipped with IFG capillary X-ray focusing collimators and an Oxford Cryosystems crystal cooling device. Computations are performed using maXus, Crystals and Raels software packages. Complex structures have been refined in non-standard ways to allow for twinning, stacking faults and composite space groups.
