To investigate the influence of a potentially N4-tripodal amine ligand on the structure and internal exchange processes of its complexes with late transition metals, five rhodium, six palladium and two platinum complexes have been prepared from seven alkyl-bridged N- heterocyclic amine tripodal ligands: tris (2-pyridylmethyl) amine,(2-(2-pyridylethyl)) bis (2- pyridylmethyl) amine, bis (2-(2-pyridylethyl))-2-pyridylmethylamine, bis (2-(2-pyridylethyl)) ...
