Module overview

Further develops understanding of inorganic chemistry and allows for a topic based and analytical approach to selected aspects of inorganic chemistry within in an applied context.

Module aims

To introduce students to advanced aspects of transition metal organometallic chemistry.

To enable an understanding and appreciation of the fundamental structures, reactivity patterns and spectroscopy associated with organometallic chemistry.

To illustrate the reactivity of selected organometallic complexes and show how these may be used as a tool for the synthesis of complex molecules.

To consider the chemistry of the lanthanoid elements.

To introduce inorganic molecular and polymeric compounds describable as rings, chains and cages.

To introduce modern developments in advanced bioinorganic chemistry

Module content

Indicative content includes:

Occurrence and structures of transition metal binary carbonyl compounds. The 18-electron rule and variants. Relationship to the MO approach. Modes of coordination of the carbonyl ligand. Phosphine complexes, cone angle. Evidence for p back bonding

Complexes of monodentate alkenes and alkynes: synthesis, structure and bonding. Hapticity.

Allyl and butadiene complexes: synthesis, structure and bonding.

Complexes of cyclo-pentadienyl, benzene and related ligands; synthesis, structure and bonding.

Metal complexes as homogeneous catalysts. Choice of catalyst. Industrial applications: Discussion of a selection of processes taken from:

Alkene hydrogenation, oxidation, hydroformylation; Tennessee-Eastman acetic anhydride process; The Fischer-Tropsch and the Monsanto processes.

The chemistry of the lanthanoid elements. The lanthanide contraction. Occurrence and extractions. Prevalence of the +3 oxidation state in compounds, and exceptions to that. Comparisons and contrasts to transition metals in optical and magnetic properties of compounds, and in complex formation. Organometallic chemistry.

Inorganic rings, chains and cages: siloxanes, phosphorus-nitrogen and sulphur-nitrogen compounds. Metal-metal bonded compounds and clusters. The Wade-Mingos –Lauher rules.

Developments in Bioinorganic chemistry. structure and function of some transition metal complexes important in biology. Oxygen carriers: haemoglobin, myoglobin, haemerythrin, haemocyanine. Electron transfer proteins: cytochromes, Fe-S proteins, copper-blue proteins. Enzymes: nitrogenase, vitamin B12, cytochrome P-450, carboxypeptidase, carbonic anhydrase.

 

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

allow students to:

rationalise the properties of 4f elements; evaluate and discuss evidence for the metal-to-ligand bonding in ; organometallic compounds; analyse the role of organometallic compounds in catalysis; critically understand the structure, bonding and reactivity of selected inorganic ring, chain and cage compounds and bioinorganic complexes; critically review aspects of current research related to these areas of inorganic chemistry; be able to apply appropriate critical, original, analytical and cognitive skills in related problem solving.

The learning and teaching methods include:



lectures 30 hours


tutorials 3 hours


Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate achievement of learning outcomes.

Thus, the summative assessment for this module consists of:

·         Examination: one 2-hour unseen written examination (Week 14, 70%) [LOs assessed 1-5]

·         Problem sheet: equivalent to 1000 words (Week 6, 20%) [LOs assessed 1-5]

·         Mid-semester test: short answer questions, 1 hour  (Week 9, 10%) [LOs assessed 1-5]

 

Formative assessment and feedback

Formative assessment and feedback are provided throughout the module in the form of in-class exercises, examples and worked problems as appropriate. Feedback is instant as model answers (full worked solutions) are given in class. Formative assessment is also evident through the provision of ‘checklists’ at the end of each section of the module that detail the areas covered in that part of the course.

Detailed and individualised feedback is given on the marked assignments within the time allowed for marking coursework.
