3-Phenyl­diazen­yl-1,2-dimethyl-1H-indole

In the title mol-ecule, C(16)H(15)N(3), the indole ring system is planar within 0.021 (3) Å and the phenyl ring is inclined to this plane by 17.32 (14)°. π-π contacts involving the pyrrole rings of inversion-related indole units [centroid-centroid distance = 3.5187 (17) Å] stabilize the crystal structure.

In the title compound, C(13)H(15)NO(2), the plane of the indole ring forms a dihedral angle of 5.26 (6)° with the ester group and the ethyl side-chain C atoms. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.

1,3-Dimethyl-1H-indole-2-carbonitrile

The title compound, C(11)H(10)N(2), crystallizes with two mol-ecules in the asymmetric unit, both of which are essentially planar (r.m.s. deviations = 0.014 and 0.016 Å). In the crystal, aromatic π-π stacking inter-actions occur [shortest centroid-centroid separation = 3.5569 (11) Å].

3,3-Dimethyl-1,2,3,4-tetra­hydro­cyclo­penta­[b]indole-1,2-dione (bruceolline E)

The title compound, C(13)H(11)NO(2), crystallizes with two mol-ecules in the asymmetric unit. The crystal packing is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains along [10[Formula: see text]], and weak C-H⋯O inter-actions.

Dimethyl 3,3′-(phenyl­methyl­ene)bis­(1H-indole-2-carboxyl­ate)

In the title compound, C27H22N2O4, the two indole ring systems are approximately perpendicular to each other, with a dihedral angle of 84.5 (5)° between their planes; the benzene ring is twisted with respect to the two indole ring systems at angles of 78.5 (5) and 86.5 (3)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, weak C-H⋯O and C-H⋯N hydrogen bonds, and C-H⋯π inter-actio...
