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. External work is performed for such institutions as University College of the Australian Defence Force Academy, University of Adelaide, RMIT University and the South Australian Museum.
