Abstract
1H NMR two-dimensional exchange spectroscopy (EXSY) reveals that in palladium(II) and platinum(II) complexes of the ligands 2,4,6-tris(2-pyridyl)-1,3,5-triazine (tpt) and 2,4,6-tris(2-pyridyl)pyrimidine (tpp), a highly novel type of fluxion occurs in which the metal moiety hurdles a C–C bond and moves from one edge of the central ligand ring to an adjacent edge; this process is accompanied by 1,4 metallotropic shifts analogous to those found in complexes of 2,2′:6′,2″-terpyridine.
