Two-dimensional molecular layers: interplay of H-bonding and van der waals interactions in the self-assembly of N,N'-dialkylsulfamides
N,N'-Dialkylsulfamide molecules assemble into solid-state structures consisting of 2D layers. The 2D layers are based on a hydrogen-bonded network of the sulfamide groups and the close-packing of alkyl groups on both sides of the 2D H-bonded network. The thickness of a 2D layer is proportional to the size of the alkyl substituents. The interplay of H-bonding and van der Waals interactions leads to stable 2D layers that pack into 3D structures.
