Potassium-Alkane Interactions within a Rigid Hydrophobic Pocket

Potassium-Alkane Interactions within a Rigid Hydrophobic Pocket

A NON‐issue: Potassium complexes of an extremely rigid and sterically encumbered NON‐donor ligand have been prepared, and the solid‐state structures (see figure) feature remarkably short potassium–alkane distances. DFT calculations highlight the presence of an electrostatic cation‐induced dipole pot...

Zusammenfassung:A NON‐issue: Potassium complexes of an extremely rigid and sterically encumbered NON‐donor ligand have been prepared, and the solid‐state structures (see figure) feature remarkably short potassium–alkane distances. DFT calculations highlight the presence of an electrostatic cation‐induced dipole potassium–alkane interaction supported by interactions between the alkane and the surrounding ligand framework.
