The field of coordination polymers containing cationic metal centers connected by organic linkers has grown tremendously during the last decade and encompasses metallosupramolecular architectures with different dimensionalities such as one-dimensional polymers, two-dimensional sheets and three-dimensional solid state materials (also called metal-organic frameworks, MOFs). Depending on the choice of the metal ion and/or the organic ligands such coordination polymers are useful materials in a variety of applications such as gas storage, catalysis, electrochromism, luminescence or electrical conductivity. Remarkably, for one of the most outstanding multifunctional organic molecules, perylene bisimide (PBI), only few coordination polymersare known to date that are all of polydisperse nature and accordingly none of them could be characterized by single crystal X-ray analysis.In this contribution we report on the metallosupramolecular self-assembly of an almost planar bay-substituted perylene bisimide dye bearing two divergent pyridyl coordinating sites with the soft Lewis acid HgCl2. The resulting one-dimesional coordination polymer features an interesting packing in the solid state that is characterized by weak intermolecular Hg���Cl interactions along the metallosupramolecular chain and slipped p-p-stacking arrangement with J-type excitonic coupling among the dyes.
