title: [2-(1H-Indol-4-yl)eth-yl]dipropyl-amine.
abstract: In the title compound, C(16)H(24)N(2), the aliphatic amine substituent is rotated almost orthogonally [C-C-C-C torsion angle = 75.7 (3)°] out of the plane of the indole unit. The amine N atom has a pyramidal configuration deviating by 0.380 (3) Å from the plane of the adjacent C atoms. All of the aliphatic groups are in extended transoid conformations. In the crystal, mol-ecules form chains along the a axis via N-H⋯N hydrogen bonds.
