270287 VO Introduction to Structural Chemistry (2018S)

The lecture is intended to provide understanding of and ability to generate structural chemical furmulae of crystallized materials. The lecture is accompanied by a various exercises and training programs.
Contents: Description and notation of structures; Nomenclature of structure types; Standardization of structures; Crystallochemical formulae; Determination of atom coordination; Structure changes under high pressures; Ionic compounds (the rules of Pauling and Bauer); Molecular structures, Intermetallics and packing of spheres (close packings, Hume-Rothery phases), Structures of nonmetals, Zintl phases (the gerneralized 8-N rule; Linking of polyhedra); Interstitial compounds (Hägg's rule); Coherent scattering from objects with disordered atom arrangement; Applications of the Debye formula; Coherent scattering of an object with ordered atom arrangement; Experimental X-ray techniques; Focusing methods in diffractometry; Rietveld refinement-powder diffraction; Structure determination from single crystals; Protein crystallography; Diffraction by helical structures.
