Course objectives

The course complements two undergraduate courses C1061 and C2062 with some interesting topics of modern inorganic chemistry and is divided in two main parts. The first one covers structure and properties of different allotropes of main group elements, homopolyatomic cations and anions of nonmetals and deals with chemistry of cage and cluster compounds of p-block elements, including boron hydrides and Zintl ions. The structure and bonding of electron deficient clusters molecules is treated by using Polyhedral Skeletal Electron Pair Theory.

The second part covers some important aspects of coordination chemistry of transition and main group elements. Methods for the study of complexing equilibria, mechanisms of the comlex formation in the aqueous solutions and the determination of stability constants are presented. Exploitation of the complex formation in practice is briefly surveyed.

Main objectives of this course can be summarized as follows:
- to provide students with a concise account of selected topics in the chemistry of the p-block elements clusters and coordination compounds.
- to understand the structure and bonding of both "electron precise" and "electron deficient" clusters.
- to learn the Wade's rules and Lipscomb's styx rules as well as their use for a prediction of borane, heteroborane and Zintl ions molecular structures.

Syllabus
