Crystal structure of 9-butyl-3-(9-butyl-9H-carbazol-3-yl)-9H-carbazole
In the title carbazole derivative, C32H32N2, the mol-ecule resides on a crystallographic twofold axis, which runs through the central C-C bond. The carbazole ring system is almost planar, with a maximum deviation of 0.041 (1) Å for one of the ring-junction C atoms. The crystal packing is stabilized by C-H⋯π inter-actions only, which form a C(7) chain-like arrangement along [110] in the unit cell.

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)°...

The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br con...
