Crystal-structure determination and Hirshfeld surface analysis of two new thiophene derivatives: (E)-N-{2-[2-(benzo[b]thiophen-2-yl)ethenyl]-5-fluorophenyl}benzenesulfonamide and (E)-N-{2-[2-(benzo[b]thiophen-2-yl)ethenyl]-5-fluorophenyl}-N-(but-2-yn-1-yl)benzenesulfonamide
In the title compounds, C(22)H(16)FNO(2)S(2) (I) and C(26)H(20)FNO(2)S(2) (II), the benzothiophene rings are essentially planar with maximum deviations of 0.009 (1) and 0.001 (1) Å for the carbon and sulfur atom in compounds I and II, respectively. In I, the thiophene ring system is almost orthog...

Sumario: | In the title compounds, C(22)H(16)FNO(2)S(2) (I) and C(26)H(20)FNO(2)S(2) (II), the benzothiophene rings are essentially planar with maximum deviations of 0.009 (1) and 0.001 (1) Å for the carbon and sulfur atom in compounds I and II, respectively. In I, the thiophene ring system is almost orthogonal to the phenyl ring attached to the sulfonyl group, with a dihedral angle of 77.7 (1)°. In compound I, the molecular structure is stabilized by weak C—H⋯O intramolecular interactions formed by the sulfone oxygen atoms, which generate two S(5) ring motifs. In the crystal of I, N—H⋯O hydrogen bonds link the molecules into R (2) (2)(8) rings, which are connected into a C(10) chain via C—H⋯F hydrogen bonds. Intermolecular C—H⋯π interactions are also observed. In compound II, the molecules are linked via C—H⋯O and C—H⋯F hydrogen bonding, generating infinite C(11) and C(13) chains running parallel to [010]. |
