  Synthesis and crystal structure determination of Mn(II) Schiff base complexes and their performance in ethene polymerization

  摘要：

  Mn(II) complexes 1-10, of which eight are novel, were prepared in high yields by reacting MnCl2 with bidentate N,N'-imine-pyridine and N,N'-imine-quinoline-type donor ligands having different kinds of chemical modifications. The complexes were fully characterized by elemental analysis, mass spectrometry and IR spectroscopy. Crystal structures of 6, 7 and 9 were determined by X-ray crystallography and the results showed that 6 has a dimeric square-pyramidal geometry, whereas 7 and 9 have distorted octahedral structures. Magnetic studies on the high spin complexes 6 and 9 showed that the former exhibits a weak intramolecular antiferromagnetic interaction through the chloride-bridging ligands with a magnetic exchange coupling J = -0.46(6) cm(-1), whereas the latter, as expected for its mononuclear structure, only shows very weak intermolecular interactions and/or zero-field splitting effects. All the complexes were activated with methylaluminoxane and investigated under low pressure (5 bar) for ethene polymerization at 60 degrees C. Complexes 1 and 6-10 showed catalytic activity. The prepared polyethenes exhibited high molar masses (296000-399000 g/mol) and high melting temperatures (133-140 degrees C). The low molar mass distribution values of 2.15-2.55 indicated single-site polymerization behavior. (c) 2013 Elsevier Ltd. All rights reserved.
