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.
