Structural Chemistry
A.Y. 2021/2022
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
Assessment methods: Esame

Single course
This course cannot be attended as a single course. Please check our list of single courses to find the ones available for enrolment.
Course syllabus and organization
Single session
Responsible
The lessons will be delivered in a mixed form: on-line and in presence (practical exercises) or entirely on-line by using different teaching methods: provide real-time lectures via live streaming and sharing audio-visual didactic material online by using the web conference system Microsoft Teams.
Course syllabus
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. Spherical and stereographic projections.
Crystal systems and symmetry. The International Tables for X-ray Crystallography. The crystal lattice (Bravais). 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.
Description of Molecular Geometry: Coordinates, molecular geometry and molecular descriptors. Cambridge Structural Database structural-correlation analysis.
Radiation sources (X-rays and neutrons). Synchrotron radiation: general principles and applications. X-ray diffraction and neutron scattering. Extended X-ray absorption fine structure (EXAFS) spectroscopy.
Small-angle neutron scattering (SANS). Applications in the chemical field.
