Description
Non-covalent interactions (NCIs), including hydrogen bonds, π-stacking and tetrel bonds, often act in concert to stabilize molecular aggregates, playing a key role in both supramolecular chemistry and molecular recognition processes. In this work, we investigate the homodimers of ortho- and para-anisaldehyde, generated in a supersonic expansion and detected using high-resolution rotational spectroscopy. The observed configurations are stabilized by a complex network of NCIs, such as hydrogen bonds, π-stacking and tetrel bonds. Theoretical calculations support the experimental observations and provide deeper insight into the nature and relative contributions of these interactions. A comparative analysis of the homodimers and monohydrated anisaldehyde complexes highlights the distinct roles and nature of the NCIs in each system. These findings contribute to a deeper understanding of how hydrogen bonds cooperate with other non-covalent forces in shaping the structure of weakly bound molecular clusters.
