Since its establishment in late 60’s the Crystallography and Coordination Chemistry of Materials Group (CCCMG), has been evolved as the main crystallographic laboratory that supports - with its unique infrastructure - the research activities of other groups within INN and NCSR "Demokritos", groups from Chemistry Departments of Greek Universities and other research centers.As a recognition of its contribution in the research in the area of chemistry, a Special Issue of the international scientific journal Polyhedron entitled "The Impact of Crystallography on Inorganic Chemistry in Greece", Vol. 28(15) 2009, was devoted to Dr. A. Terzis, ex-director of CCCMG, on the occasion of his retirement.
Powder diffraction studies are also well developed in CCCMG by means of data analysis with the Rietveld method. Apart from purely crystallographic research, the CCCMG group has been involved in the areas of Molecular Magnetism since 1995, and has developed its own synthetic projects since 2000 which cover various aspects of coordination chemistry such as chemical reactivity studies of transition-metal complexes and models of Bioinorganic systems.
The expertise of the personnel covers almost all areas of research in X-ray crystallography, i.e. single crystal studies by X-ray diffraction methods; crystal structure analysis by the Rietveld Method of X-ray powder diffraction patterns; crystal structure physical property correlation studies of organic superconductors, HTc superconducting ceramic materials, hard magnetic materials, molecular magnets and transition metal and rare earth coordination compounds ; thin film and nanoparticles studies by X-ray diffraction techniques; instrumentation for powder diffraction applications. Besides routine crystal structure determinations we deal with disordered crystals, modulated structures and twin crystals. XRD powder diffraction studies is a key activity for INN and NCSR “Demokritos” and almost all the materials prepared at INN as powders and thin-films are characterized under the supervision of the group. Routine characterization of powder diffraction samples is performed via the extensive use of powder diffraction data bases. Since 2010 the expertise of Dr V. Psycharis on X-Ray Powder Diffraction is provided to large Greek Pharmaceutical Industries for RND and quality control applications.
The Laboratory of Crystallography was set up in the late 60’s with the acquisition of a Philips XRD instrument. The first single-crystal diffractometer (Syntex) was acquired in 1979. Ever since, the infrastructures are constantly upgraded. Today 4 diffractometers are in full operation, which consist a unique infrastructure for Greece. Two of the are for single crystal studies (Rigaku R-axis SPIDER and Crystal Logic double-beam diffractometer), and two for powder diffraction and thin Film applications (SIEMENS D500 and Rigaku Smart Lab).
