Abstract

Thia-bridged diquinoline tetrabromide 7 has been synthesised and found to be a further example of the tetrahalo aryl inclusion host family. The X-ray crystal structures of the (7)₂·(benzene) and (7)₂ (chloroform) inclusion compounds are described and analysed. In both, the hosts assemble by means of two new types of centrosymmetric aryl edge-edge packing motifs. The first type is a C-Br⋯N dimer which generates chains of 7 molecules that are cross-linked by the second interaction, a double bifurcated Br⋯Br⋯H motif. The included guest molecules are enclosed within host molecular pens in both structures. Novel S⋯Br interactions also play an important role in linking these building blocks.
