Training objectives
- -The course deals with the electronic structure and reactivity of transition metal compounds, the electron transfer processes, and the structure and properties of inorganic solid state.
The course includes theoretical and practical aspects. Introduction to techniques and procedures important to the successful practice of inorganic- chemistry. Development of a proper scientific approach to the execution of experiments and interpretation of the resulting data. The student should have the ability of programming the inorganic synthesis, characterizing the reaction products and understanding their chemical properties. Prerequisites
- -Basic Knowledge of Inorganic Chemistry, bond theory, chemical kinetics and molecular symmetry.
Course programme
- -The teaching encompass 40 h of theory and 48 h of experiments in the Inorganic Chemistry laboratory. During the frontal teaching the following topics are treated . Application of group theory. Crystal field and ligand field theory. Molecular orbitals of transition metal complexes. Electronic states and electronic spectra. Main coordination numbers. Isomers. Kinetics and mechanisms of ligand substitution. Metal carbonyls. Metal nitrosyls. Nitrogen complexes. Organometallic compounds: alkyl and olefin complexes, metallocenes. Band theory. Semiconductors, Marcus theory. Mixed valence compounds. Defects. Non-stoichiometric compounds. Diffusion of atoms and ions. Solid electrolytes. Metal Oxides.
The experiments, which follow, are performed in the Inorganic Chemistry laboratory. Preparation and characterization of coordination compounds based on ruthenium (II): UV- Vis and 1H NMR characterization. Application of electrochemical methods in inorganic chemistry: cyclic voltammetry, half wave potential, reversibility criteria, kinetic and diffusional control of an electrochemical process.
Determination of the electronically excited state properties: determination of excited state oxidation and reduction potential from spectroscopic and electrochemical data. Sensitization of wide band-gap semiconductors in solar energy conversion processes.
No reports on the different experiments are requested. These will be discussed during the oral examination Didactic methods
- -The course is held through 40 h of teaching lessons, with the help of slides which help explaining the different subjects and 48 h of laboratory training on the preparation, spectroscopic and electrochemical characterization of coordination compounds.
Learning assessment procedures
- -The purpose of the examination is to verify the level of knowledge on the different subjects treated during the course and evaluate the ability to apply this knowledge to the solution of synthetic problems and to the characterization of inorganic compounds. The exam is oral and involves four questions. The exam is passed if the student answers satisfactorily to at least three questions.
