Cyclopalladated and cycloplatinated complexes of 6-phenyl-2,2′-bipyridine: platinum-platinum interactions in the solid state

Abstract

The crystal and molecular structures of the complexes [PdLCl] and [PtL(MeCN)][PF₆](HL = 6-phenyl-2,2′-bipyridine) have been determined; in each case, the cyclometallated ligand behaves as a terdentate C,N,N-donor, analogous to 2,2′:6′,2″-terpyridine; in the case of the platinum complex metal–metal interactions are observed, giving rise to alternate long–short contacts [3.28(1), 4.59(1)Å] between canons.
