1-[6-(1H-Indol-1-yl)pyridin-2-yl]-1H-indole-3-carbaldehyde

In the title compound, C₂₂H₁₅N₃O, the dihedral angle between the two indole units is 33.72 (3)°. The mol­ecular structure features a weak intra­molecular C—H...N inter­action. In the crystal, weak C—H...O and C—H...π inter­actions, forming a two-dimensional network parallel to the bc plane.

9-[4-(Azido­meth­yl)phen­yl]-9H-carbazole-3-carbo­nitrile

In the title compound C₂₀H₁₃N₅, the dihedral angle between the carbazole ring system (r.m.s. deviation = 0.027 Å) and the pendant benzene ring is 55.08 (6)°. One of the azide N atoms is disordered over two positions in a 0.65 (2):0.35 (2) ratio. In the crystal, aromatic π–π stacking is observed [minimum centroid–centroid separation = 3.6499 (13) Å] as well as inversion-dimers connected by pairs of weak C—H...π inter­actions.
