Inorganic 7 mainly focuses on "coordination chemistry".
Coordination chemistry has developed from valence bonding theory → crystal field theory → ligand field theory → molecular orbital theory. I have learned simple crystal field theory and ligand field theory in Inorganic Chemistry 2 class, so in Inorganic Chemistry 7, I would like to further develop how to use coordination chemistry and why metal complexes have their physical properties. Learning to explore  as an academic subject.

Then, we will learn about (1) the structure of complexes, (2) the valence bonding theory, (3) crystal field theory, and (4) ligand field theory. For (1), we will learn about the coordination structure, geometric isomers, and optical isomers of complexes, and introduce what kind of complexes there are along with their functionality. In addition, you will be able to actually count the number of isomers of the complex. In (2), we will learn about the properties of complexes from the 18-electron rule, electron-precise compounds, hybrid orbitals, and π-backdnating bonds. Students will learn about the structures and physical properties formed by the valence electrons of complexes. In (3), we will be able to understand the structure, magnetism, and other physical properties of the complex simply by considering the energy splitting by the d-orbital ligand. We will learn that the physical properties of metal complexes can be predicted from the coordination structure and the electronic properties of the ligands. For (4), the molecular orbital theory is treated with consideration of the total orbitals. , Finally, we will treat the crystal field theory spectroscopically, treat it as a weak field and a strong field term, respectively, and will be able to understand Tanabe-Sugano's energy diagram.

Since we are running out of time for the topics in the second half, I will briefly introduce them each time in the first 15 minutes. If the opportunity permits, I will briefly explain the most advanced science being conducted at the Tadokoro Lab and the professors at the external Lab.

In order to understand the properties of metal complexes, learn about d-orbital splitting, learn the basics of the valence bond method, crystal field theory, and ligand field theory, and understand why the properties of metal complexes occur. Become. In addition, you will be able to understand the Tanabe-Sugano energy diagram, which is important for the spectroscopic interpretation of complexes.

You will be able to design and synthesize functional materials using what kind of physical properties of metal complexes. Also, how the splitting of the d orbital becomes from the shape of the metal complex,
It becomes possible to predict how the states of electrons and spins change.

Since this is a specialized lecture on coordination chemistry, you should understand inorganic chemistry 1 and inorganic chemistry 2. In particular, it is desirable to review the parts that were taught in Inorganic Chemistry 2 and Inorganic Chemistry Seminar 2. Make sure to take the short test as it will be randomly given.

Evaluate at 50% or more in the final exam, and less than 50% in the normal score and short tests.

Any short tests can be brought in, so it is desirable to understand it during class time. About the final exam
I'm thinking of making it possible to bring in handwritten notes.
