9-Bromo-9-borafluorene

The title compound, C(12)H(8)BBr, crystallizes with three essentially planar mol-ecules (r.m.s. deviations = 0.018, 0.020 and 0.021Å) in the asymmetric unit: since the title compound is rigid, there are no conformational differences between these three mol-ecules. The crystal packing resembles a herringbone pattern.

7-Benzyl­oxymethyl-9-bromo-6-chloro-9-deaza­purine

The title compound, C(14)H(11)BrClN(3)O, crystallizes with two independent mol-ecules in the asymmetric unit. In the crystal, the molecules are linked by C-N⋯Br halogen bonds, as well as weak methyl-ene C-H⋯π, phenyl C-H⋯π, C-H⋯Br and phenyl C-H⋯O(ether) inter-actions.

The title compound, C(19)H(13)BrClN, was synthesized by N-alkyl-ation of 4-chloro-1-(chloro-meth-yl)benzene with 3-bromo-9H-carbazole. The carbazole ring system is essentially planar, with a mean deviation of 0.028 Å, and it makes a dihedral angle of 91.2 (3) Å with the plane of the benzene ring.
