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

摘要

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 [De = Cu(II) or Hg(II), Ar = Ph, 3-DeD mu C6H4, or 4-DeD mu C6H4, 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.
