Cobalt(II), Nickel(II) and Copper(II) Complexes with 2-Hydroxyimino-4,5-Diaza-3-phenyl-6-Amino-6-Mercapto-3-hexene

Abstract

Some homo-binuclear metal complexes of the type [(HAPAME)M(H₂O)₂]₂X₂, where HAPAME is a Schiff's base ligand obtained by the condensation of thiosemicarbazide with 1-phenyl-1,2-propanedione-2-oxime, M = copper(II), nickel(II) and cobalt(II) and X = Cl^–, Br^–, OAc^–, NO₃^– or ClO₄^– have been isolated. Infrared spectra of the complexes suggest that the ligand coordinates of the metal ion through both of its imine nitrogen, oxime oxygen and thionyl sulphur. Reflectance spectra of the complexes indicate octahedral geometry around the metal ions.
