Front Cover: Three in One: The Versatility of Hydrogen Bonding Interaction in Halide Salts with Hydroxy‐Functionalized Pyridinium Cations (ChemPhysChem 18/2021)

The Front Cover shows one of the three types hydrogen bonding observed in hydroxy-functionalized halide salts. Here, anion forms a bond to hydroxy group and interacts with ring system cation at same time. versatility structures demonstrates importance non-covalent interactions, particular role bonding.
