Alternating perpendicular 1-D channels in the supramolecular structure of the copper(II) complex [Cu(pyterpy)2](PF6)2 · CH3OH · 0.5 CH2Cl2 (pyterpy = 4′-(4′′′-pyridyl)-2,2′:6′,2′′-terpyridine)

The reaction of 4′-(4′′′-pyridyl)-2,2′:6′,2′′-terpyridine (pyterpy) with copper(II) yields the novel mononuclear [Cu(pyterpy)2](PF6)2 complex. The crystal structure shows that the Cu(II) center is coordinated by the terpyridine domains of both pyterpy molecules, while the pyridyl tails remain uncoordinated. Intermolecular π-π stacking interactions between the cations in the crystal result in the formation of alternating 1-D linear channels which run in perpendicular directions.
