【 摘 要 】

In the title indole derivatives, C22H16N2O5S, (I) and C20H15NO3S2, (II), the sulfonyl-bound phenyl rings are almost orthogonal to the indole ring system, subtending dihedral angles of 88.33 (10) and 87.58 (16)°, respectively. In both compounds, the sulfonyl S atom has a distorted tetra­hedral geometry [O—S—O = 119.98 (9) and N—S—C = 104.01 (8)° for compound (I) and O—S—O = 120.08 (18) and N—S—C = 104.91 (14)° for compound (II)] and the sum of the bond angles at N indicates sp2 hybridization. The mol­ecules of both (I) and (II) feature intra­molecular C—H⋯O hydrogen bonds that generate S(6) ring motifs with the sulfone O atom. In the crystals, mol­ecules of (I) are linked by C—H—O hydrogen bonds, forming R44(18) ring motifs while mol­ecules of (II) are linked by C—H—O and C—H—S hydrogen bonds, forming R22(12) ring motifs. Compound (II) was refined as an inversion twin.
