Knowledge and understanding: the teaching is mainly focused on the study of advanced inorganic chemistry and coordination chemistry. The nature of the bond and the properties of polyatomic molecules and coordination compounds as well as their electronic nature will be approached through the Group Theory. The course provides basic and advanced knowledge of transition metals and coordination chemistry based on electronic configuration, oxidation state, coordination geometry and on the different nature of the ligands. Peculiar properties of transition metals and coordination compounds such as vibrational modes, electron spectroscopy, magnetism and luminescence will be studied.
Applying knowledge and understanding: the basis acquired on Group Theory and bond theories will be applied to describe electronic and magnetic properties of coordination compounds. Group Theory skills will be applied to the study and understanding of electronic properties of coordination compounds such as polarity, chirality, vibrational modes, electron spectroscopy, and magnetism.
Making judgements: Practical experimental work performed in laboratory gives the manual and intellectual skills required to prepare and characterize coordination compounds. The critical elaboration of the experimental data, and the reports containing the explanation of the laboratory experience along with the comparison with the data present in the literature, will give the student a deeper insight on the knowledge acquired.
Communication skills: the students learn to report and argument on the knowledge acquired.
Learning skills: Group Theory gives to the student important skills to get a deep view on the Chemistry studied during the firs level degree. Subjects such as the chemical bond, the construction of molecular diagrams, the interpreting of electronic d-d spectra, and the magnetism will be treated to a higher level and correlated to the properties of transition metals and coordination compounds.
The followings pre-requisites are required:
1) Knowledge of the main bond theories acquired in the courses of General Chemistry and Inorganic Chemistry.
2) Knowledge of the theoretical principles of the main spectroscopic techniques.
3) Trigonometry and matrix algebra basis.
4) The nomenclature of coordination compounds.
• The Group Theory rules and their application to the understanding of the chemical bond and properties of coordination compounds.
• Ligand field theory and Molecular Orbital diagrams construction.
• Electronic properties and UV-visible spectroscopy.
• Coordination Compounds: definition and systematic approach to coordination number, geometry, nomenclature and isomerism (geometrical, optical, bonding, coordination, ionization, hydration, etc..).
• The chemistry of transition elements: General and periodical trends (electronic configuration - properties, oxidation states - properties)
- The elements of the first series of transition
- The elements or the second and third transition series
• General aspects of the chemistry of the elements of the block f
• Synthesis, kinetic and thermodynamic stability, reactivity and reaction mechanisms. Trans effect.
• New applications and new frontiers of coordination chemistry.
Practical experiments in the lab illustrate and demonstrate the main topics previously treated from a theoretical point of view.
The course is distributed during two semesters and is divided in two parts each one composed by 4+2 CFU corresponding to 48 hours of frontal lessons and 24 hours of practical laboratory experience. Moreover, 16 hours of assisted study per semester are granted to students, dispensed by frontal sessions of exercise and either individual or small group explanations on specifically required topics.
In case of emergency, lessons could be dispensed on live-streaming and the recording distributed by the official academic platforms.
Verification of learning
The evaluation of the student will be based on:
1) A written test with exercises regarding the different topics reported in the program.
Two partial tests positively performed during the course can be evaluated in place of the final written test.
2) Original reports prepared by the students on the results obtained during the laboratory experiences.
3) An oral presentation and/or seminar prepared on either a ligand or metal group chosen by the student.
4) Participation and motivation demonstrated by the student during the course.
The above described tests will be evaluated in 30th, the final evaluation will be calculated as an average of the single scores.
In case of emergency, the above-mentioned tests could be changed according to the prescriptions and rules dictated by the Rector.
