Síntesis, caracterización espectroscópica y electroquímica de complejos de níquel(II) y cobalto(II) con nuevos ligandos N2S2,N,N’-alquil-bis(2-amino-1-ciclopentencarboditioato de etilo y bencilo)

Abstract

The synthesis of nickel(II) and cobalt(II) complexes with the new nitrogen-sulphur ligands, ethyl-N,N'-alkylbis(2–amino–1– cyclopentencarbodithioate) with alkyl = ethylene (L1), propylene (L2), butyl (L3) and benzyl-N,N'-butyl-bis(2–amino–1– cyclopentencarbodithioate) (L4), and their characterization (UV-Visible, FTIR, 1H- and 13C- NMR, elemental analysis, mass spectra and cyclic voltametry) are reported. The spectroscopic and electrochemical properties of metallic complexes have a potential importance as models in inorganic biomimetic.
