Abstract

Title full: The preparation and structural characterization of a double-helical binuclear dicobalt(II) complex of 2,2′: 6′,2″: 6″,2‴: 6‴, 2″″-quinquepyridine; the x-ray crystal structure of acetato(O,O′)bis (2,2′: 6′,2″: 6″,2‴: 6‴, 2″″-quinquepyridine)dicobalt(II) hexafluorophosphate tris-acetonitrile solvate. The reaction of cobalt(II) acetate with 2,2′: 6′,2″: 6″,2{less-than with dot}: 6{less-than with dot},2″″-quinquepyridine (L) in acetonitrile results in the spontaneous assembly of a binuclear double helical complex. The electrochemical behaviour of this compound is complex. The driving force for the assembly of the complex is probably associated with the close stacking contacts between approximately co-planar pyridine rings; there are no direct metal-metal interactions.
