Structural Chemistry
A.Y. 2020/2021
Learning objectives
The course provides an introduction to X-ray diffraction structural techniques, paying particular attention to experimental aspects and interpretation of data. The aim of the course is therefore to make the student understand what structural information can be obtained and how from this type of investigation.
Expected learning outcomes
Students will gain ability to interpret and use structural information of crystalline substances.
Lesson period: Second semester

Course syllabus and organization
Single session
Responsible
Lesson period
Second semester
The course will take place in the second semester for 4 hours weekly divided into lessons lasting 2 hours each. If necessary, the lessons will be delivered in a mixed form: online and in presence (practical exercises) or entirely online by using different teaching methods: real-time lectures via live streaming and sharing audio-visual didactic material online (video recordings of power point presentations).
Course syllabus
Crystal systems and symmetry. The International Tables for X-ray Crystallography. X-ray production. The crystal lattice. X-ray diffraction. Bragg's Law. The reciprocal lattice. Structure factors and Fourier Syntheses. Experimental methods for single-crystal structure determination. Structure solution and refinement. Interpretation of results. Crystallographic Databases.
Fundamental aspects of growth processes: a) Homogeneous and heterogeneous nucleation; b) supersaturation and mass transport; kinetics and mechanisms of crystal growth; c) crystal growth techniques from solution. Morphology of the crystals: crystal classes, crystal forms and Miller indices. Theories for crystal habit prediction.
