| Description:
| Aims: To introduce the principles of the chemistry of the 4f and 5f series of elements (lanthanides and actinides) To introduce the principles of the chemistry of the heavy transition metals with particular reference to metal-metal bonded polynuclear complexes. Learning Outcomes: After studying the Unit, students should be able to: * explain the importance of the 4f and 5f valence orbitals in determining the chemistry (and contrasts between the chemistries ) of the lanthanide and actinide elements * describe variations in oxidation state and the uses of coordination and solid state f-element compounds in synthesis and catalysis * rationalise the magnetic and spectroscopic behaviour of the f-elements and explain how these properties are exploited in a variety of applications * describe and explain the formation (or lack of formation) of multiple bonds to 4f and f element centres * Explain the systematic trends across the d-block elements. * Contrast the differences down individual d-block triads. * Determine whether metal-metal bonds are present in a polynuclear complex. * Rationalise the structures of early and late transition metal clusters using electron counting schemes. Skills: Numeracy (F, A), Problem solving (T, F, A) Scientific writing (F, A), Independent working (F) Group working (F) Content: Introduction to the 4f elements, the lanthanides. Shapes and nature of the f-orbitals. Oxidation states and effects of the lanthanide contraction. Extraction and isolation of the lanthanides. Solid state 4f element compounds, halides and oxides. Divalent and tetravalent lanthanide compounds. Electronic configurations, magnetism and spectroscopy of lanthanide derivatives. Lanthanide coordination chemistry and shift reagents and use in organic synthesis. Organolanthanide chemistry and organometallic catalysis. Actinide occurrence and synthesis. The 5f orbitals; comparison to lanthanide chemistry. Applications of actinide elements. Actinide oxidation states and coordination chemistry. Actinide spectroscopy and magnetism. Actinide organometallic chemistry. A description of the chemistry of the second and third row d-block elements. The contrast between the chemistry of these heavier d-block elements with those of the first row. Selected chemistry of a d-block triad. Magnetic and spectroscopic properties of the complexes of compounds of these elements. A discussion of the presence of metal-metal bonding in polynuclear d-block complexes and methods of electron counting in early and late transition metal clusters. |
