Abstract


Palladium(II) complexes containing di-(2-pyridyl)-N-methylimine (1), di-(2-pyridyl)methanol (2) and di-(2-pyridyl)methyl-N,N-diethyldithiocarbamate (4) ligands were synthesized and characterized by 1H and 13C NMR in solution, IR and X-ray single crystal diffraction. Crystal structures of cis-dichloro[di-(2-pyridyl)-N-methylimine]palladium(II) (5), cis-dichloro[di-(2-pyridyl)methanol]palladium(II) (6) and cis-dichloro[di-(2-pyridyl)methyl-N,N-diethyldithiocarbamate]palladium(II) (7) showed a bidentate coordination mode of the di-(2-pyridyl)methane derivatives 1, 2 and 4. In these complexes is observed the formation of a five-membered chelate ring with the iminic ligand 1 and six-membered chelate rings with the pyridinic ligands 2 and 4. In all complexes the palladium atom displays a distorted square planar geometry.
