The Pi – Halogen Dimer (PHD) Interaction: A Versatile New Construction Unit for Crystal Engineering

, , , &
Pages 173-186 | Published online: 31 Aug 2006
 

ABSTRACT

The pi – halogen dimer (PHD) interaction is a new type of intermolecular packing motif discovered in certain crystalline diquinoline compounds. It consists of a combination of one aromatic offset face-face (OFF) interaction, and four aromatic pi – halogen interactions, and provides a compact building block for the self-assembly of lattice inclusion compounds. This article reviews the current state of knowledge about this new solid-state construction motif.
