Module code: CH311
Credits: 5
Semester: 2
Department: CHEMISTRY
International:

	Overview
	Introduction to crystal field theory to understand the optical and magnetic properties of d-block transition metal co-ordination complexes. Use of group theory to look at the effects of high symmetry crystal fields on the incomplete d-orbitals. Construction of Orgel diagrams to predict the ground and excited electronic states and by applying Selection rules, predict the absorption transitions of co-ordination complexes. Organometallic Chemistry: Meaning of Organometallic complexes, electron counting, oxidation state and electronic configuration of organo-transition metal complexes. General overview of the CFT (Crystal Field Theory) and MO (Molecular Orbital) theory applied to organometallic complexes. ¿pi-acceptor and ¿pi-donor ligands. Back bonding. Ligands: Carbon Monoxide (CO): MO of CO, coordination to a metal centre. Carbonyl complexes, synthesis and applications. Carbenes: coordination to a metal centre. Fischer and Schrock carbenes, synthesis and applications. pi-ligands: back bonding and hapticity. Cyclopentadienyl ring. Ferrocene. Synthesis and reactivity of ferrocene. MO of ferrocene. Chemistry of the f-Block elements and compounds: Material covered includes: Lanthanoids (lanthanides) - electronic configuration; oxidation states; M3+, M4+ and M2+ ions; the lanthanoid contraction, coordination and organometallic complexes; UV-vis spectra, luminescent and magnetic properties. Actinoids (actinides) - electronic configuration; oxidation states; coordination and organometallic complexes; UV-vis spectra and magnetic properties. The ground state term symbol for f-block metal ions. Trends in the elements, ions or compounds of the f-block, and comparisons with the chemical/physical properties of those of the s- and d-blocks.

	Learning Outcomes
	On successful completion of the module, students should be able to: Explain metal-carbon bonding in organometallic complexes. Construct synthetic protocols for organometallic complexes and explain their reactivity. Count electrons of an organometallic complex, draw the structure and determine the oxidation state and the electronic configuration of the metal centre. Discuss the optical and magnetic properties of co-ordination complexes of the transition metals in terms of crystal field theory. Discuss aspects of the physical/spectroscopic and chemical properties of f-Block elements/compounds. Explain or predict aspects of the physical/spectroscopic and chemical properties of f-Block elements/ compounds.

Teaching & Learning methods

Assessment

Module Graded (numeric value) or Ungraded (Pass/Not Passed): Graded
Continuous Assessment detail(s): Comprises of laboratory/practical classes and workshops (including satisfactory attendance).

Assessment type	Weighting	Duration
Continuous Assessment	30%
University scheduled written examination	70%	90 minutes
Other	0%
Total	100%	90 minutes

Pass standard: 40%
Could the result of this module be capped? No
The pass standard is 40%, subject to a minimum mark of 40% in practical class work (satisfactory attendance at practical classes is also a requirement). The module mark will be capped at 35% in cases where a student does not pass the continuous assessment component of the module (ie. continuous assessment mark of less than 40%; absent from more than 2 labs in one module; absent from more than 2 labs in one semester). Students who obtain an “E capped” mark who choose to re-sit the written exam in August cannot improve their module mark, which will remain capped at 35% (35% is within the compensation threshold). Students who obtain an “F capped” mark who choose to re-sit the written exam in August can improve their module mark to a maximum of 35%, ie. the module mark is capped at 35% (35% is within the compensation threshold). NOTE: Students should familiarise themselves with the Departmental Rules & Regulations outlined in the 3rd year manual.
Penalties: There is no option to repeat the continuous assessment component of the module within the same period of study.

	Autumn Supplementals/Resits
	Are supplemental/resit registrations permitted? Yes There is an opportunity to re-sit the written examination within the same period of study, ie. Autumn. The continuous assessment mark is carried forward to the Autumn examination. Please refer to assessment rules. University scheduled written examination (Autumn): 90 minutes Is Supplemental Continuous Assessment registration permitted? No Is Supplemental Continuous Assessment capped? No
