The molecules of 2-benzoyl-1-benzofuran, C 15 H 10 O 2 , (I), interact through double C—HO hydrogen bonds, forming dimers that are further linked by C—HO, C—Hπ and π–π interactions, resulting in a three-dimensional supramolecular network. The dihedral angle between the benzoyl ...

The recent surge of interest in the control of molecular organization in both the solution state (i.e. self-assembly) and the solid state (i.e. crystal engineering) has led researchers to recognize increasingly the importance of weak noncovalent interactions. The design and synthesis of an effic...
In particular, such interactions in the second coordination shell of metal ions in proteins may modulate the structure and reactivity of the metal ion site in functionally significant ways. Recently, π–π interactions between metal ion coordinated histidine imidazoles and aromatic amino acids have ...

A reasonable explanation is that Anion- π interactions prevent the loss of X · from the [NO 2 -B15C5 + Cu + X] + ions. The presence of the electron-withdrawing NO 2 group causes the aromatic ring to be poor in electrons and thus its enhances its interactions with anions. For the ...
