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, hav
e isomorphous crystal structures. The crystal packing is mainly determined
by intermolecular C-H . . .O and C-H . . . pi interactions. These interacti
ons are very similar in (Ia) and (Ib). Additional intermolecular C-H . . .
Cl interactions appear less important and are different in (Ia) and (Ib). T
he different positions of the Cl atoms result in small variations of the cr
ystal packing of the two compounds.
