Synthesis and structure of Co(II), Ni(II), and Cu(II) complexes with Schiff bases, condensation products of 2-amino-4,8-naphthalenedisulfonic acid and aromatic carbinols
摘要:
Ten new cobalt(II), nickel(II), and copper(II) complexes with Schiff bases obtained by condensation of 2-amino-4,8-naphthalenedisulfonic acid with carbinols (salicylaldehyde, benzoin, and 2-hydroxy-1-naphthaldehyde) have been synthesized. The compounds were studied by the X-ray powder diffraction method, thermal analysis, magnetic susceptibility and electric conductance measurements, and IR, EPR, diffuse reflectance, and EXAFS spectroscopy. The compositions of coordination cores in the complexes have been established. It was noted that the diversity of the resulting polyhedra is determined by the synthesis conditions, specific features of the stereochemistry of the ligands, and the electronic structure of the complex-forming metal.
