摘要:
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 . . . pi 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.
