Goal: The lecturers will introduce you into the world of coodination chemistry both on a synthetic and a physico-chemical points of view.
Content:
General concepts in coordination chemistry
- Metal ions and ligands
- Nomenclature of complexes
- Geometry of complexes with different coordinence
- Isomerism in coordination compounds
Thermodynamic and kinetic approaches of complexes in solution
- Formation constants: definition and experimental determination
- Chelate effect, a central concept in coordination and supramolecular chemistry
- Applications to supramolecular recognition of cations
- Inertia and lability, essential kinetic notions for understanding complexes reactivity
- Synthesis of complex dedicated ligands: crown-ethers, Schiff bases, polypyridine, ...
Electronic structure of metal complexes
- Counting electrons in complexes: the Green's method
- 16/18 electrons rule
- Reactions implying metal complexes
- Application to homogeneous catalysis
- From crystal field to ligand field
- Construction of Molecular Orbitals diagrams of octahedral metal complexes
- Insight into spectroscopic series
Optical properties of metal complexes
- Spectroscopic terms of metal complexes including lanthanide complexes
- Electronic spectroscopy of metal complexes
- Emission of light by metal complexes
Magnetic properties of monometallic complexes
- Origins of the magnetic properties of metal complexes
- Magnetic susceptibility
- From Van Vleck equation to Curie law
- Departures from Curie law
- Spin Cross-Over phenomenon: from definition to applications
Article Analysis: Every student will study and present an article dealing with an application strongly related to the contents of the lecture.
Labworks: Four topics of the lectures will be illustrated during four experimental work sessions of four hours each
- Synthesis and study of the luminescent properties of lanthanide complexes
- Biomimetic model of molybdic oxo-tranferase enzyme
- Synthesis and properties of a iron(II) spin Cross-Over compound [1]
- Synthesis and study of a mixed-valence compound
To anticipate the Lab work, the practical work is written by each student in a dedicated Labwork notebook [2].
Prerequisites: Basics knowledge of general chemistry (electronic structure of the elements, thermochemistry...), in group theory and in coordination chemistry (general definitions, crystal field theory)
