3,6-Dibromo-9-(4-chloro-benz-yl)-9H-carbazole.

The title compound, C(19)H(12)Br(2)ClN, was synthesized by N-alkyl-ation of 1-chloro-4-(chloro-meth-yl)benzene with 3,6-dibromo-9H-carbazole. The carbazole ring system is essentially planar (mean deviation of 0.028 Å) and makes a dihedral angle of 74.6 (3)° with the plane of the benzene ring.

3,6-Dibromo-9-(4-bromo-benz-yl)-9H-carbazole.

The title compound, C(19)H(12)Br(3)N, was synthesized by N-alkyl-ation of 1-bromo-4-(bromo-meth-yl)benzene with 3,6-dibromo-9H-carbazole. There are two unique mol-ecules in the asymmetric unit. The carbazole ring system is essentially planar, with a mean deviation of 0.0402 Šfor one mol-ecule and 0.0279 Šfor the other. The carbazole planes are inclined to the benzene ring planes at dihedral angles of 58.3 (3) and 71.1 (3)° in the two mol-ecules.
