CHEM203 - Main Group and Coordination Chemistry
CHEM 203 Main Group and Coordination Chemistry is an 18-point paper available in the second semester.
It focuses on how the concepts and techniques of chemical science can be used to gain an understanding of the synthesis, structure and reactivity of inorganic and organometallic molecules.
The topics covered in CHEM 203 are:
Shape, Symmetry and Structure (6 lectures)
- An introduction to the importance of symmetry in chemistry.
- Symmetry elements, symmetry operators and their consequences in discrete molecules.
- Point groups, character tables, and their use in describing chemical bonding.
- An introduction to space groups.
The Periodic Table and Chemical Bonding: Chemistry of some main group elements including main group organometallic chemistry (12 lectures)
- The periodic table, its history and development. Periodic trends within the table.
- A review of chemical bonding. Lewis Structures, the Octet rule, VSEPR, Valence bond theory and Molecular Orbital theory.
- Main group Lewis acids and bases, hard and soft acid and bases (HSAB) principles.
- Bonding in main group compounds, with particular emphasis on the boron hydrides.
- Structural methods in main group chemistry. Multinuclear NMR and ESI-MS.
- Bonding of organic groups to main group elements: σ-donor, σ-donor/π-acceptor, σ,π donor/β-acceptor;
- Hapacity, Metal alkyls; reactivity; β-elimination
Chemistry of Coordination Compounds (12 lectures)
- Transition metal (TM) complexes, nature of TM ligand bonds, classification of ligands.
- Stereochemistry of coordination compounds, coordination numbers 4, 5 and 6.
- Stereoisomerism, geometrical and optical.
- Configuration of TM ions, hard and soft acid and bases (HSAB) principles.
- Electronic properties of TM ions.
- Crystal-field theory, hole formalism, application to octahedral, tetrahedral and square planar geometries.
- Electronic spectra and magnetism as a tool to investigate the properties of coordination compounds.
- Jahn-Teller effect and its consequences.
Chemistry of lanthanoids and their complexes (6 lectures)
- Introduction to lanthanoid metals (Ln’s) and their ions, including electronic configurations, general properties and periodic trends.
- Ln coordination compounds: coordination numbers 7 to 12; hard and soft acid and base (HSAB) principles applied to Ln ions.
- The basis of two types of practical applications of Ln complexes: as Magnetic Resonance Imaging (MRI) agents; as luminescent materials.
Lecture times and venues
Semester 2 Wednesday, Thursday and Friday at 11:00 am
Semester 2 Monday or Thursday or Friday at 2.00 pm (Chemistry Labs, second floor, Science I)
The laboratory course is designed to complement lecture material with an emphasis on synthetic, analytical and spectroscopic techniques.
The objectives of the laboratory course are:
- to provide exposure to experimental techniques that are essential to a study
of inorganic and organometallic compounds
- to learn to handle chemicals, glassware and scientific equipment safely
- to learn to prepare, purify and characterise inorganic and organometallic
- to become proficient at the accurate recording and presenting of laboratory
work in written reports
- to use laboratory time and resources efficiently
Expectations at the completion of the course
- An appreciation of the breadth and excitement of modern inorganic chemistry
and its relationship to the discipline of chemistry and other sciences
- An understanding, through the selected lecture themes, of how concepts of
bonding, coordination chemistry and solid-state structure can be used to
predict and rationalize the synthesis, structure and reactivity of inorganic
and organometallic compounds
- Through self-directed learning, stimulation of students to evaluate the
limitations and extensions of these concepts and apply them to examples
from several disciplines
- The attainment of practical, problem-solving and time-management skills
All students will have acquired knowledge and understanding of the foundation concepts of inorganic chemistry.
Global perspective, interdisciplinary perspective, lifelong learning, scholarship, communication, critical thinking, environmental literacy, information literacy, self-motivation, teamwork
Two-hour written examination 70%
Laboratory assessment 30%
