Abstrakt:	Dimethyl sulphoxide (DMSO) molecules in their all-organic solvates were shown to interact with arene rings of organic molecules via DMSO-O(lone pair)⋯π(arene) or DMSO-S(lone pair) ⋯π(arene) interactions in approximately 5-6% of their crystal structures, often in conjunction with conventional hydrogen bonding involving the O(DMSO) atom, resulting in zero-, one- and two-dimensional supramolecular architectures. Zero-, one- and two-dimensional supramolecular architectures were also found to be sustained by parallel S==O⋯π(arene) interactions operating in combination with hydrogen bonding.
