Role of coordination compounds in catalysis, molecular electronics and bioanorganic chemistry
Annotation
The lecture is aimed at the basic priciples of coordination chemistry including the nature of coordination bond and the electronic structure of cations in the ligand field approximation. Introduction to stability constants, stereochemistry and isomerism, substitution and electron transfer reactions, template effect and concept of self-assembly, and overview of various types of coordination compounds and their role in catalysis, molecular electronics and bioanorganic cemistry are another topics of the lecture.
