Syllabus
Prerequisites: Inorganic Chemistry - Part I
Target skills and knowledge: This course will provide a survey of the chemistry of the d-block metals (groups 3-12) and will introduce some theoretical concepts useful for the interpretation of their behavior. During the lab practice the students will be introduced to some basic unit operations and techniques of the inorganic laboratory and will carry out experimental observation concerning concepts and phenomena described in the classroom lessons. The following instrumental techniques will be employed: UV-Vis spectroscopy in solution, FT-IR spectroscopy (mid and far-infrared), GC-MS, magnetic balance.
Examination methods: The exam includes a preliminary written test and a single oral on both the classroom program and the lab practice (no separated oral exams allowed).
Students are admitted to the oral part after:
1) attending all the scheduled hours for the lab practice and 75% of the classroom introducing the lab (lessons on lab safety compulsory; sign-in and sign-out required).
2) submitting of the lab reports assigned within the given deadlines;
3) getting a positive score in the preliminary written test.

Students failing, for any other reason, to meet the above requirements for the lab will have to repeat the practice the year next (no recovery lab periods are scheduled).

Students failing the exam will have to repeat the written preliminary test.
Assessment criteria: The final grade will depend on the score of:
the lab reports;
the oral exam.
The latter will deal with both the general part and the lab practice (including the experiments not dealt with in the reports).

Lab reports found to be copied or translated will not be evaluated and the student will have to repeat the lab practice the year next (no recovery lab periods are scheduled). For this purpose anti-plagiarism software might be used.

The reports will be evaluated according to the following criteria:
1) meeting the guide lines given for writing the report;
2) meeting the deadlines for the delivery of the reports;
3) ability to exclude unimportant or not essential information;
4) order and coherence in dealing the subject;
5) proper use of the language, of quantities, of significative figures, of units of measurements;
6) use of proper concepts, models and theory;
7) ability in connecting the experimental results and the theory;
8) independence of the work.


The oral exam will be evaluated according to the following criteria:
1) ability and readiness in focusing on the topics;
2) ability to illustrate the topics in an independent way;
3) level of insight;
4) fluency;
5) ability to connect concepts and subjects;
6) use of proper language.
Course unit contents: • The d-Block and the transition metal series, electronic configurations. Solid state structure of metals: hard sphere model, closed lattices, fundamentals of the band theory. Physical, physico-chemical and chemical properties of the d-block elements and their changes across periods and groups.
• Ligands and their nature, coordination modes, nomenclature (names and formulas). Coordination numbers and common geometries from di- to hexacoordination. The Kepert model and the balance between steric and electronic factors. Isomerism in coordination chemistry.
• Crystal field theory: simmetry of d-orbitals, splitting of d-orbitals in the octhedral and tetrahedral field; dependance of the crystal field force on the charge of the central ion, the principal quantum number of the d-orbitals and the nature of the ligands (spectrochemical series). High-spin and low-spin complexes. The crystal field stabilization energy (CFSE) and changes thereof with the electronic configuration of the central ion. Tetragonal distorsions; square planar field.
• Molecular orbital theory applied to octahedral complexes: sigma complexes; pi-donation and pi-acidity. Interpretation of the spectrochemical series and of the 18-electron rule.
• Electronic spectroscopy of the complexes: electronic spectra, d-d bands, charge-transfer bands, selection rules, typical values of ε. Electron repulsion, atomic terms, Hund rules, spectroscopic terms for high spin complexes, Orgel and Tanabe-Sugano diagrams. The Racah parametrs, the nephelauxectic effect, the ligand-field theory.
• Paramagnetism and diamagnetism, the spin-only assumption, magnetic susceptivity and its relationship with the magnetic moment. Ferro- and ferrimagnetism, antiferromagnetism.
• The effect of CFSE on thermodinamic properties of compounds of the metals of the first transition series: lattice energy of di-a nd trihalides, standard enthalpy of hdration of the divalent cations, spinel structure.
• Step-wise and global thermodinamic formation constants of metal complexes: the chelate effect; the Irving-Williams series.
• Substitution in octahedral complexes: mechanisms and criteria to identify them; the crystal field activation energy and kinetic inertness.
• Descriptive chemistry of the transition metals: occurrence and methods of extraction of the elements. Chemical behaviour of the metals of the first transition series and of representative metals of the second and third transition series. Metal oxides, hydroxides and halides; aqueous and coordination chemistry.
• Lab practice: description of the specific risks of the experimental work to be done, of the prevention measures and the good practice rules; test on lab safety; description of the experimental procedure; discussion of the experimental results. Experiments: synthesis and purification of transition metal complexes; nitration of chromium acetylacetonate; measure of ΔO and B from the electronic spectra of metal complexes with Tanabe-Sugano diagrams; linkage isomerism in cobalt(III) complexes and geometric isomerism in copper(II) complexes; rate of aquation of pentaamminochlorocobalt(III); aqueous redox chemistry of vanadium.
Planned learning activities and teaching methods: The course is comprised of a general part (theory and descriptive chemistry of groups 3-12) and of a practice in transition metal chemistry. The general part is delivered as classroom lessons (40 hours, in italian), also with slide projection. The practice is comprised of classroom lessons (10 hours, in italian), devoted to the lab safety, the introduction and the comments to the experiments, and the execution of the experiments (48 hours). For the latter the students will work in small groups (two-three persons each). At the end of the lab practice the student will have to write two reports, each on one of the experiments. The reports must be written individually even though the experiments are carried out as a team work.
Additional notes about suggested reading: Handsout (only on the general part on theory; not on descriptive chemistry; in italian).
Guide to the lab practice (safety and experimental procedures).
Guidelines for the final report on the lab practice.
The resources for the students are available in the e-learning platform of the Department of Chemical Sciences (login required: use the credential for the on-line services of the University of Padova).
