Synthesis and studies of bromide complexes of copper (II) and cadmium (II) with arsenic containing ligands

Abstract :

The interaction of K2[MBr4] (where M = Cu (II) or Cd (II)) with tetrasubstituted arsonium nitrates in aqueous–alcoholic solutions has been studied. As a result of the reaction, tetraomocuprates (II) or tetraomocadmates (II) of arsonium have been obtained [Ar2(R)(R1)As]2[MBr4], Ar=–C6H5, m–CH3C6H4; R1=–CH3, –C2H5, –CH2–CH=CH2, –CH2–C ; M= Cu or Cd. The composition and structure of synthesized compounds was established by elemental analysis, as well as various physical and chemical methods of analysis. The IR–spectrum of the synthesised compounds indicates the quaternization of the atom of arsenic and its presence in the complex cation. The cationic–anionic composition of the samples under study has been established by determining the molar conductivity in dimethyl formamide. These analyses indicate the formation of three ions as a result of dissociation
