| (*)More specifically, upon completion of the course they will be able to
- understand and explain the specific bonding concepts of organometallic and coordination compounds, both of main group as well as transition metals (k2, k3, k4, k5).
- predict the reactivity of organometallic compounds from their bonding properties (k5, k6).
- suggest reaction routes for the preparation of organometallic and coordination compounds (k5, k6).
- understand specific aspects of analytical methods relevant to molecular inorganic compounds and know their limitations. They can assess the corresponding experimental findings (e.g. simple heteronuclear 1D-NMR-spectra, single crystal X-ray diffraction, etc.) (k2, k3, k4, k5, k6).
- deduce structural, electronic, optical and magnetic properties based on the ligand field theory and simple molecular orbital concept (k3, k4, k5, k6).
- modify the properties of coordination compounds by variation of the ligand environment (k4, k5, k6).
- understand the bonding situation in compounds/clusters bearing metal-metal multiple bonds (k2, k3, k4)
- identify elementary reactions of coordination compounds (k2, k3, k4).
- translate concepts they know from organic chemistry to molecular inorganic compounds (k5, k6).

(*)Underlying concepts and details of
- organometallic chemistry of main group and transition metals; stability/lability of M–C bonds; -H-elimination
- main group metal organometallic chemistry: synthesis, structure, bonding and reactivity with a particular focus on lithium- and magnesium-organyls
- reactivity of Zn- and Hg-organyls.
- important characterization methods used for molecular metalorganic compounds: NMR-spectroscopy, single-crystal X-ray diffraction (SCXRD), elemental analysis, mass spectrometry, etc.
- NMR-spectroscopy: 1D-spectra of heteronuclear NMR, coupling patterns, VT-NMR, paramagnetic NMR, Evan’s method
- SCXRD: basic principle of diffraction, information which can be gained from SCXRD.
- trends of transition metals (electron configuration, electronegativity, oxidation states, melting points), relativistic effects and lanthanide contraction.
- the structure of coordination compounds of d-block transition metals: ligands, isomerism, geometries
- ligand field theory: orbital splitting, electron configuration, ligand field stabilization energy, color and magnetism, high/low-spin configuration, Jahn-Teller-effect
- simplified MO theory of transition metal complexes, effective atomic number, spectro-chemical series, electron counting
- specific ligands and their properties:
o carbon monoxide and metal carbonyls, bonding in metal carbonyls (pi-backdonation)
o pi-bonded ligands (olefins, aryl, cyclopentadiene).
o phosphines: pi-acceptor properties, Tolman’s parameters, chiral phosphines
- fundamental reactions of metal complexes: association, dissociation, substitution, oxidative addition/reductive elimination, insertion, cis-effect, electron transfer
- metal-metal-bonds in transition metal complexes: from single to sextuple bond.
- isolobal analogy
