This course will examine, in detail, the theory and the practice of the x-ray structure determination.
We will begin with a quick review of the description of the crystal structures of binary, ternary and other solids.
The second chapter consists of the basics such finite and infinite symmetry elements, point groups, space groups, unit cell, crystal systems, Bravais lattices, stereographic projection of point groups and the nomenclature of space group tables, their projections and the use of the International Tables for Crystallography.
In the third chapter, we will develop the theory of the x-ray diffraction on single crystal and powder material, by introducing the Bragg’s law, Miller indices, reciprocal lattice, Ewald sphere, Laue group, structure factor, systematic absences, peak intensity, peak position, peak shape, Rietveld refinement on powder sample, etc.
After learning about the strategy of the data collection and reduction, we will solve the phase problem using the Patterson, heavy atom and direct method and we will finish with the structure refinement, which is illustrated with examples from all synthetic disciplines (inorganic, organometallic and organic) using Shelx-program.
The last chapter explores the different techniques used for the growth of single crystal suitable for single crystal x-ray diffraction and the notion of twining in crystallography.
During the class, we will visit the x-ray laboratory and use some crystals provided by the
students for the demonstration and full structure determination.
