| Popis: | The synthesis and structural characterization of Ni(II) complexes derived from N1,N4-bis(pyridin-2-ylmethylene)butane-1,4-diamine ( L1 ) and N1,N4-bis(1-(pyridin-2-yl)ethylidene)butane-1,4-diamine ( L2 ) is described. The paramagnetic Ni(II) complexes NiL1 and NiL2 were fully characterized and their structures unequivocally determined by single crystal X-ray diffraction techniques. The molecular structures of NiL1 and NiL2 exhibited the ligands L1 and L2 coordinated in a κ 4 - N,N,N,N -tetradentate fashion. The subtle changes in the ligands defines the ionic o neutral nature of the complexes. Furthermore, in the solid state both complexes exhibit extended hydrogen-bond networks. |
