SemesterAutumn Semester 2021
LecturersH. Grützmacher, J. Grützmacher
Periodicityyearly recurring course
Language of instructionEnglish

AbstractGeneral bonding concepts
AIM and ELF as descriptors of electronic structures
GCMT model, carbenes and carbene analogues, homo and heteronuclear unsaturated bonds
Electron precise cluster, electron deficient cluster, and special cluster
General concepts and definitions of inorganic polymers, polysilanes,
polysiloxanes, polyphosphazenes
ObjectiveThe course starts with an introduction into general concepts allowing to understand why main group element and transition metal compounds from the higher periods show different properties when compared to their lighter congeners. The Atom in Molecule (AIM) Theory and Electron Localization Function (ELF) will be introduced as means to interpret the electron density distribution in molecules. Carbenes and carbene analogues will be discussed as building blocks for compounds with unsaturated bonds which in turn may serve as precursors to inorganic polymers.
Electron counting rules allow to distinguish different type of clusters which can be divided into electron precise cluster, various electron deficient cluster (for example Wade-Mingos-Cluster), and special cluster.
An introduction into general concepts for syntheses and analyses of inorganic polymers will be given. Specifically, polysilanes, polysiloxanes, and polyphosphazenes will be discussed and possible applications of these polymers will be highlighted.
Recent literature will be provided and discussed jointly by the participants of the course (flipped classroom).

The man goal of the lecture is to provide a general understanding of the current literature in the field of modern inorganic chemistry with respect to building blocks used for the synthesis of cluster, polymers, and materials.
Lecture notesA handout of the presented material will be distributed to the participants of the course. Articles from recent literature will be provided and discussed in the course.
LiteratureOrginal literature is indicated in the course material.
Prerequisites / NoticeBasis for the understanding of this lecture are the courses Allgemeine Chemie 1&2, and Anorganische Chemie 1: Übergangsmetallchemie.
