• Resumen

  • Two complexes have been synthesized through the reaction of copper(II) acetate dihydrate with 4,4´-bipyridine. Both were characterized by elemental analysis, magnetic moment, FT-IR spectroscopy, and thermogravimetric analysis. Semiempirical structural DFT studies of [Cu2(CH3COO)4(4,4.bipy)2]n and 4,4´ bipyridine were carried out. 4,4´-Bipyridine acts as bidentate ligand, breaking the Cu2(CH3COO)4 unit and acting as bridge between the metal centers, yielding a polymeric structure bearing monodentate acetate groups. The compounds [Cu2(CH3COO)4(4,4-bipy)2]n and [Cu2(CH3COO)4(4,4-bipy)2(H2O)2]n have magnetic moments of 1.83 and 1.77 B.M, respectively. These values are higher than those of copper (Il) acetate monohydrate (1.4 B.M).
