Chemistry of coordination compounds with laboratory

A.Y. 2021/2022
Overall hours
Learning objectives
The course is designed to understand the key features of coordination compounds, and to provide the basics of traditional coordination chemistry and organometallic chemistry, both in theoretical and practical aspects.
Expected learning outcomes
The student will be able to understand: the structure and the stereochemistry of transition metal complexes; The metal to ligand interaction; The principal aspects concerning the stability and the reactivity of coordination compounds; Their role in chemical synthesis.
Course syllabus and organization

Single session

Lesson period
First semester
The lessons of the theoretical part of the course will be given online in a synchronous mode. All recordings of the lessons will be made available to the student for the duration of the semester through the Ariel website of the course. When necessary online student meeting will be also organized. The exam mode remains unchanged.
As far as the laboratory is concerned, some experiences will be selected and conducted and the students will be divided into small groups. All indications will be reported on Ariel website of the course.For both laboratory experiences and the other experiences, material will always be provided on Ariel website (ppt and / or video files).
Course syllabus
a) classroom lectures (7 credits).
Introduction, coordination numbers and geometries, isomerisms (structural, geometrical, optical), nomenclature and formulae, mono- and poly-dentate ligands. Crystal field and ligand field theories. Metal-ligand interactions of σ- and -bonding types. Electron counting. Thermodynamics (formation constants, chelate and macrocyclic effects) and kinetics (lability, inertness and electronic configuration). Substitution, association, inter-exchange and electron transfer mechanisms.
Complexes with M-H bonds (classical and non-classical hydrides, agostic interactions), M-Sn, M-N (imides, nitrenes e nitrydes), M-S, M-O (alkoxydes, acetylacetonates, oxo, peroxo e superoxo), M-X (X:halogen). Complexes with -type ligands (carbonyls, nitryles, isonitryles, nitrosyls, dinitrogen, phosphanes). -type complexes (olefines, acetylenes, allyls, cyclopentadienyls and aromatic rings).
b) laboratory experiments (3 credits).
Syntheses of inorganic and coordination compounds, specifically selected to present the most representative separation and purification techniques and some important aspects of the properties and the chemical behavior of metals and ligands (oxidation state of metals, type of ligands, coordination modes, chelate effect, geometrical, ligand and optical isomerism).
Prerequisites for admission
Courses of General and Inorganic Chemistry and Inorganic Chemistry I
Teaching methods
Traditional frontal lessons whose attendance is strongly recommended and laboratory practical experiences of mandatory attendance.
Teaching Resources
Recommended textbooks:
- P.Atkins, T.Overtone, J.Rourke, M.Weller, F.Armstrong - Inorganic Chemistry - Oxford University Press (2006), Fourth edition
- G.L. Miessler, D.A.Tarr - Chimica Inorganica - ed. Piccin (2012)
- Lecture slides provided by the teacher
Assessment methods and Criteria
The exam comprise a report on the experiences conducted during the lab exercises and a written test on the topics developed during the frontal lessons. This written test requires answers to about 8 questions over a period of about three hours.
