Intermolecular Interactions in Heavy Main Group Element Compounds

Within the framework of the SPP 1807 "Control of London dispersion interactions in molecular chemistry" our group works on heavy main group elements as dispersion energy donors in inter - and intramolecular interactions. The joined project with Prof. M. Mehring's group at the TU Chemnitz focuses on the rich phenomenology of heavy main group atom interactions in coordination and supramolecular chemistry. While the coordination group in Chemnitz synthesizes and characterizes new structural motifs of, for example, Bismuth, Arsenic and Atimony compounds, our group carries out computations for the detailed analysis of the balance of donor - acceptor interactions and dispersion forces in these compounds.

While applications reveal a broad range of phenomena for a given system and allow chemists to identify new and promising structures and reactions in cooperation with the group of Giovanni Bistoni we also develop novel tools for the investigation of intermolecular interactions focusing on the combination of quantitative accuracy of high-level ab-inito methods and the chemical insight obtained from fragmentation and analysis approaches.
