The X-ray diffraction on single crystal species as well as powdered and amorphic phases are experimental methods used
in the research carried out at the Department of Crystallography. When necesary - IR spectroscopy and hot-stage
microscopy are used. The aim of the X-ray crystal structure analysis is the investigation of the stereochemistry
of organic compounds, such as natural products (e.g. derivatives of alkaloids, saccharides, amino acids and steroids)
as well as drug molecules and compounds of biological importance.
Determination of molecular structure and analysis of intermolecular interactions give important information on the
mechanism of drug activity. The problems studied in our department include polymorphism, solvation and
isostructurality, which are of great importance to the pharmaceutical industry.
In 1999, thanks to KBN grant, a single crystal X-ray diffractometer KM4 was purchased.
Applied crystallography, mainly small angle X-ray scattering (SAXS) method, is used for studies of the porous phase structures (for example zeolites, silica gels, glass, carbons, aluminium oxides and zirconium oxides) and starch. Our SAXS instrument allows us to investigate inhomogeneous samples of the 1-80nm range. The X-ray powder diffraction is used to determine structure of metallic compounds, ordered porous material, polymers and other. In accordance to the agreement of long-standing research services (due to 9 grants from International Center for Diffraction Data, USA) dozens of reference of X-ray powder diffraction data have been determined.
