(E)-2-Methyl-3-(2-methyl-2-nitrovinyl)-1H-indole and (E)-3-(2-methyl-2-nitrovinyl)-2-phenyl-1H-indole

Abstract: In the title compounds, C₁₂H₁₂N₂O₂, (I), and C₁₇H₁₄N₂O₂, (II), respectively, the indole rings are planar and the vinyl groups lie out of the indole planes, making dihedral angles of 33.48 (5) and 41.31 (8)°, respectively. In (II), the dihedral angle between the phenyl and indole ring planes is 32.06 (6)°. In both molecules, the double bond connecting the methylnitrovinyl group and the indole nucleus adopts an E configuration. Notwithstanding the differences in space group [C2/c for (I) and P2₁2₁2₁ for (II)], the mode of packing of compounds (I) and (II) is determined by similar intermolecular N-HO hydrogen-bonding interactions, forming chains that run parallel to [101] in (I) and [001] in (II).

Formula: C₁₂H₁₂N₂O₂ and C₁₇H₁₄N₂O₂
