Methyl 3-(1H-indol-3-yl)propanoate
The mol-ecule of the title compound, C(12)H(13)NO(2), adopts an essentially planar conformation (r.m.s. deviation = 0.057 Å). In the crystal, the mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, generating chains along [201].

(Z)-3-(1H-Indol-3-yl)-2-(3-thienyl)acrylonitrile, C15H10N2S, (I), and (Z)-3-[1-(4-tert-butylbenzyl)-1H-indol-3-yl]-2-(3-thienyl)acrylonitrile, C26H24N2S, (II), were prepared by base-catalyzed reactions of the corresponding indole-3-carboxaldehyde with thiophene-3-acetonitrile. 1H/13C NMR spectral data and X-ray crystal structures of compounds (I) and (II) are presented. The olefinic bond connec...

In the title compound, C(10)H(7)BrN(2), the non-H atoms, except the N atom of the acetonitrile group and the C atom bonded to it, lie in the least-squares plane defined by the atoms of the indole ring system (r.m.s deviation = 0.019 Å), with the N and C atom of the cyano group displaced by 2.278 (1) and 1.289 (1) Å, respectively, out of that plane. In the crystal, N-H⋯N hydrogen bonds link the ...
متن کامل4-[Bis(1H-indol-3-yl)methyl]benzonitrile
In the title mol-ecule, C(24)H(17)N(3), the didhedral angles formed by the mean planes of the indole ring systems and the benzene ring are 86.44 (7) and 86.96 (7)°. The dihedral angle between the two indole ring systems is 72.08 (6)°. In the crystal, inter-molecular bifurcated (N-H)(2)⋯N hydrogen bonds link mol-ecules into sheets lying parallel to (010).
