Synthesis and study of complexes of copper(II) and mercury(II) with triaryl- and diarylalkylarsine oxides

Resumo

The interaction of copper(II) and mercury(II) nitrates with triaryl- and diarylalkylarsine oxides has been studied. The reactions in aqueous-alcoholic solution have yielded [M(OAsPh₃)₄](NO₃)₂ and [M(OAsRAr₂)₄](NO₃)₂ cationic complexes [М = Cu(II) or Hg(II), Ar = Ph, 3-МеC₆H₄, or 4-МеC₆H₄, R = Et, Pr, i-Pr, Bu, or i-Bu]. Composition and structure of the products have been elucidated by a set of chemical and physico-chemical methods. IR spectroscopy data have revealed that the bond between the ligand and the metal ion is formed via the oxygen atom of arsenyl group.
