Abstract

The indole derivative [3,3':3',3''-terindolin]-2'-one bis(dimethyl sulfoxide), C₂₄H₁₇N₃O ⋅ 2(C₂H₆OS) has been synthesized using green protocol in 89% yield, and its crystal structure is determined by X-ray structure analysis. The crystals are monoclinic, space group P2₁/n, Z = 4. Bicyclic indole moieties form dihedral angle of 60.32° with each other; the oxindole ring is twisted with respect to them at angles of 86.08° and 76.93°. The crystal structure is stabilized by N–H⋅⋅⋅O, N–H⋅⋅⋅S, and C–H⋅⋅⋅O hydrogen bonds involving both DMSO solvate molecules.

摘要

吲哚衍生物[3,3'：3'，3''-terindolin] -2'-双（二甲基亚砜），C ₂₄ H ₁₇ N ₃ O⋅2 （C ₂ H ₆ OS）已用绿色合成。收率89％，其晶体结构通过X射线结构分析确定。晶体是单斜晶体，空间群P 2 ₁ / n，Z =4。双环吲哚基团彼此形成二面角为60.32°。羟吲哚环相对于它们以86.08°和76.93°的角度扭曲。晶体结构通过涉及两个DMSO溶剂化物分子的N–H⋅⋅⋅O，N–H⋅⋅⋅S和C–H⋅⋅⋅O氢键来稳定。
