Propyl 2-(1H-indol-3-yl)acetate

In the title compound, C13H15NO2, the acetate group [C-C(=O)-O] makes a dihedral angle of 62.35 (13)° with the mean plane of the indole ring system [maximum deviation = 0.011 (3) Å]. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming helical chains propagating along [010].

2-(1H-Indol-3-yl)acetohydrazide

In the title compound C(10)H(11)N(3)O, the mean plane of the indole ring system (r.m.s. deviation 0.0131 Å) subtends a dihedral angle of 87.27 (5)° to the almost planar acetohydrazide substituent (r.m.s. deviation 0.0291 Å). In the crystal, bifurcated N-H⋯(O,N) and N-H⋯N hydrogen bonds involving the pyrrole N-H grouping combine to form zigzag chains along a. Additional N-H⋯O contacts from the h...

2-(1H-indol-3-ylcarbon­yl)acetonitrile

The title compound, C(11)H(8)N(2)O, crystallizes with two crystallographically independent mol-ecules in the asymmetric unit which are approximately perpendicular to each other [79.97 (6)°]. The indole ring system is planar [r.m.s. deviation = 0.010 (1) Å]. The crystal structure is stabilized by inter-molecular C-H⋯N and N-H⋯O inter-actions.

In the title compound, C(20)H(18)N(2)O(3), the C=C bond of the acrylonitrile group that links the indole and the 3,4,5-trimeth-oxy-phenyl rings has Z geometry, with dihedral angles between the plane of the acrylonitrile unit and the planes of the benzene and indole ring systems of 21.96 (5) and 38.94 (7)°, respectively. The acrylonitrile group is planar (r.m.s. deviation from planarity = 0.037 ...

Methyl 2-(5-fluoro-1H-indol-3-yl)-2-oxoacetate

The indolyl portion of the title mol-ecule, C(11)H(8)FNO(3), is flat, the five- and six-membered rings making a dihedral angle of 0.815 (6)°. Inter-molecular N-H⋯O hydrogen bonds link adjacent mol-ecules into a linear chain. Slipped π-π stacking inter-actions between two neighboring indole groups further consolidate the mol-ecules into a three-dimensional supra-molecular architecture [centroid-...
