The present study gives a comprehensive insight into anion–p interactions in the solid state, focusing on purely organic and charge-neutral fluorophenyl groups bearing a positive charge located at a side chain. The detailed statistical analysis of a series of structural data sets shows the geometrical variability of anion–p bonding in the solid state. It reveals the directing substituents at the arene as key elements for the positional preferences of anions above p-systems. The structural variety of the interaction between anions and electron-deficient arenes is considered by use of the hapticity concept. Together with new evaluation criteria, two helpful tools to understand and describe anion–p interactions in the solid are used.

Effects of alternative electron acceptors on the activity and community structure of methane-producing and -consuming microbes in the sediments of two shallow boreal lakes Rissanen, Antti; Karvinen, Anu; Nykänen, Hannu; Peura, Sari; Tiirola, Marja; Mäki, Anita; Kankaala, Paula (Federation of European Microbiological Societies; Oxford University Press, 2017)The role of anaerobic CH4 oxidation in controlling lake sediment CH4 emissions remains unclear. Therefore, we tested how relevant EAs (SO42−, NO3−, Fe3+, Mn4+, O2) affect CH4 production and oxidation in the sediments of ...
Halogen bond in crystal engineering : structural studies on crystals with neutral ruthenium centered complexes and 1-(4-pyridyl)-4-thiopyridine zwitterion as halogen bond acceptors Ding, Xin (2020)This work focuses on using both ruthenium complexes and a newly synthesized organic zwitterion as halogen bond (XB) acceptors to construct a series of crystal structures and to investigate the selectivity of halogen bond. ...
Electron-deficient trifluoromethyl-substituted sub-components affect the properties of M4L4 tetrahedral cages Struch, Niklas; Topic, Filip; Rissanen, Kari; Lützen, Arne (Royal Society of Chemistry, 2017)Two supramolecular tetrahedral cages based on a new electron-deficient trifluoromethyl-substituted pyridylimine ligand are synthesised by sub-component self-assembly. Their structures are characterised by NMR und UV-Vis ...
Kujala, Tuomo; Lasch, Annegret; Mäkelä, Jakke (Association for computing machinery, 2014)We tested a commercial in-car navigation system prototype against the NHTSA criteria for acceptance testing of in-vehicle electronic devices, in order to see what types of in-car tasks fail the acceptance test and why. In ...
