CHEMISTRY OF TRANSITION ELEMENTS AND LABORATORY - MOD.1

The course falls within the core educational activities of the Master Study Programme in Chemistry and Sustainable Technologies, which allow the student to deal with a chemical problem in its various articulations and with consistent use of the current technical-scientific language. The specific training objective of the course is to provide advanced knowledge of inorganic chemistry, in particular regarding the determining aspects of structure, spectroscopic properties, magnetism and reactivity of the coordination and organometallic compounds of transition elements. The course aims to develop skills that allow students to design and implement the synthesis of a coordination compound having specific physical-chemical properties.

1. Knowledge and understanding.
I) Knowing the metal-ligand interactions and understanding the influence of the ligands on the electronic structure of the metal centres.
II) Knowing the relationships between the electronic structure of the metal centres and the geometry of the coordination compounds.
III) Understanding the relationships between complex structure and spectroscopic and magnetic properties.
IV) Understanding the reactivity of the transition elements as a function of the electronic structure and of the coordination sphere.
2. Ability to apply knowledge and understanding.
I) Being able to use the concepts learned to foresee and logically interpret the chemical-physical properties of a complex.
II) Being able to propose coherent and feasible syntheses of coordination and organometallic compounds.
3. Ability to judge
I) Being able to evaluate the effects induced by changes in the electronic configuration of metal centres and in the coordination sphere.
II) Being able to recognize the basic elements determining the stability of a complex, so as to recognize similarities and differences between coordination compounds.
4. Communication skills
I) Being able to use the appropriate scientific-technical terminology and symbols to discuss the course contents.
II) Being able to interact constructively with the teacher and with the other students.
5. Learning skills
I) Being able to synthesize in an autonomous way the salient aspects of the concepts expressed in class.
II) Being able to make logical connections between the topics of the course.
III) Being able to apply the theoretical concepts learned in the inorganic synthesis laboratory.

The prerequisite is to have achieved the training objectives of the General Chemistry and Inorganic Chemistry courses provided in the three-year degree courses in Chemistry. It is necessary for the student to know the basic concepts concerning atomistic and chemical bonding. The student must also be familiar with the chemistry of the main groups elements and with the basic organic chemistry. Finally, the student must possess basic knowledge of spectroscopy typical of the three-year degree courses in Chemistry.

In relation to the training objectives and expected learning outcomes, shown in the relevant sections, the contents of the course can be divided as follows:
I) Coordination compounds: theory, coordination number and geometry, kinds of ligands, nomenclature.
II) Transition elements: definition, electronic configuration, main features.
III) Complexes with sigma-donor, pi-donor and pi-acceptor ligands. Carbonyl, isocyanide, phosphine and nitrosyl complexes: synthesis and some properties.
IV) Transition element chemistry: general considerations.
V) Coordination and organometallic chemistry of group 4 elements (Ti, Zr, Hf). Oxidation states, coordination geometry, ligands, reactivity, applications.
VI) Coordination and organometallic chemistry of group 5 elements (V, Nb, Ta). Oxidation states, coordination geometry, ligands, reactivity, applications.
VII) Coordination and organometallic chemistry of group 6 elements (Cr, Mo, W). Oxidation states, coordination geometry, ligands, reactivity, applications.
VIII) Coordination and organometallic chemistry of group 7 elements (Mn, Tc, Re). Oxidation states, coordination geometry, ligands, reactivity, applications.
IX) Coordination and organometallic chemistry of group 8 elements (Fe, Ru, Os). Oxidation states, coordination geometry, ligands, reactivity, applications.
X) Coordination and organometallic chemistry of group 9 elements (Co, Rh, Ir). Oxidation states, coordination geometry, ligands, reactivity, applications.
XI) Laboratory: Synthesis and characterization of coordination and organometallic compounds in relation to the theoretical contents of the course. Conductimetry, spectroscopic (IR, UV-VIS, PL, NMR) and magnetic characterization of transition metal complexes.

For the study and the deepening of the theory:
I) F. A. Cotton, G. Wilkinson, C. A. Murillo, M. Bohmann, Advanced Inorganic Chemistry, 6th ed .; Wiley-Interscience, 1999.
II) J. Ribas Gispert, Coordination Chemistry; Wiley-VCH, 2008.
III) C. E. Housecroft, A. G. Sharpe, Inorganic Chemistry; 4th ed., Pearson, 2012.
IV) Lecture and laboratory notes and additional teaching materials available on Moodle platform.

The assessment of learning takes place through an oral test, which consists of a series of questions to which the student must respond by demonstrating to know and be able to expose the topics of the entire program (see the content section) with correct language and use of scientific chemistry symbols. The oral exam lasts from 30 minutes to 45 minutes depending upon the clarity and consistency of the answers to the questions asked. There are at least three questions, the first of which concerns laboratory work.

Teaching is organized in lectures including examples. The laboratory proposes experiences of synthesis and characterization closely linked to the contents delivered frontally. In Moodle educational material concerning lectures and laboratory is available and downloadable. The participation to at least 80% of the laboratory activities is compulsory.
