title: Crystal structure of 9-butyl-6-[2-(pyridin-4-yl)ethen-yl]carbazol-3-amine.
abstract: The asymmetric unit of the title compound, C23H23N3, consists of two mol-ecules, A and B, with different conformations. In mol-ecule A, the dihedral angle between the carbazole ring system (r.m.s. deviation = 0.028 Å) and the pyridine ring is 20.28 (9)° and the N-C-C-C torsion angle of the butyl side chain is -63.4 (3)°. The equivalent data for mol-ecule B are 0.065 Å, 48.28 (11)° and 61.0 (3)°, respectively. In the crystal, the components are connected by weak N-H⋯N hydrogen bonds, generating [030] C(14) chains of alternating A and B mol-ecules.
