Learning objectives
At the end of the course the student is able to know, understand and apply the essential concepts of the chemistry of coordination compounds, in particular as regards the metals of block d. The student will show: a good knowledge of the most common coordination numbers and associated geometries, understanding of the quantum mechanical basis for describing complexes, understanding the thermodynamic and kinetic basis of the chemistry of complexes.
The student will develop those communication skills, that ability to learn and make connections between the various topics, and which will allow to deal with the scientific literature about coordination chemistry, even in its various application aspects.
Prerequisites
Basic knowledge of inorganic and organic chemistry
Course unit content
Introduction to the chemistry of coordination compounds (complexes). Werner's theory (primary and secondary valence in a metal ion). Nomenclature of coordination compounds. Ligands (denticity, coordination modes, cyclic ligands). Coordination number, coordination geometry. Isomerism and chirality in complexes. Hard and soft acids and bases (HSAB) theory.
The bond in the coordination compounds: outline of crystal field theory. Introduction to the theory of molecular orbitals (covalent model). Electronic and magnetic properties of the complexes. Jahn-Teller effect.
Thermodynamic aspects of the chemistry of coordination compounds. Selectivity of a ligand for a metal ion. Ionophores. Kinetic aspects of the chemistry of coordination compounds, substitution reactions and trans effect. Redox reactions. Template reactions.
Some examples of coordination compounds in: bioinorganic chemistry, medicine, industrial chemistry, materials science.

Assessment methods and criteria
The achievement of knowledge and understanding of the course contents will be ascertained through an oral test. If the health emergency makes it necessary, the exam will still be oral, but in remote mode.
