Notes:
The title compounds, N-[5-(4-chlorophenyl)furan-2-ylmethyl]-4-methyl-N-(prop-2-ynyl)benzenesulfonamide, (Ia), and N-[5-(2-chlorophenyl)furan-2-ylmethyl]-4-methyl-N-(prop-2-ynyl)benzenesulfonamide, (Ib), both C21H18ClNO3S, have isomorphous crystal structures. The crystal packing is mainly determined by intermolecular C—H...O and C—H...π interactions. These interactions are very similar in (Ia) and (Ib). Additional intermolecular C—H...Cl interactions appear less important and are different in (Ia) and (Ib). The different positions of the Cl atoms result in small variations of the crystal packing of the two compounds.
