摘要:
The synthesis and structural characterization of Ni(II) complexes derived from N1,N4-bis(pyridin-2-yl-methylene) 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 kappa(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. (C) 2015 Elsevier B.V.
