Crystal Structure of 1,3,6-Tribromocarbazole

Abstract

The crystal structure properties of 1,3,6-tribromocarbazole (1) are: orthorhombic, space group Pna21 with a = 17.3110(3)A, b = 4.5608(2)A, c = 14.9606(2)A, V = 1181.17(6)A3, Z = 4, R1 = 0.0267, wR2 = 0.0594 for the 2677 reflections (I > 3σ(I)). The solid state structure of 1 consists of layers of stacked molecules, with hydrogen bonding between the N-H bonds and the Br atoms of molecules on neighbouring stacks (H…Br distances = 2.840(1)A).
