Abstract
A range of symmetrical 4',4"-disubstituted 2,2':6',2":6",2"'-quaterpyridine s has been prepared and their coordination behaviour with metal ions having a preference for tetrahedral and octahedral geometries has been studied. T he new ligands reacted with copper(I) and silver(I) salts ro form dinuclear double-helical complexes; reaction with nickel(II) or cobalt( II) salts ga ve mononuclear species. The crystal structures of three mononuclear complex es are reported and demonstrate that the ligand binds in a tetradentate mod e to the equatorial plane of the octahedral metal centre.
