Synthesis and characterization of some Co(II), Ni(II) and Cu(II) complexes with 2,3-di(thiobutane) aniline

Abstract

The new cobalt (II), nickel (II) and copper (II) complexes with 2,3-di(thiobutane) aniline in the coordination sphere were prepared. All the complexes were characterized by IR, UV-vis. Spectroscopy, conductivity and magnetic measurements and some of them by metal content. Conductivity data in DMSO showed that some complexes are 1:2 (M:L) electrolytes which assigning the formula [M(L)3]Cl2 while the other complexes are non-electrolyte which assigning the formulas [M(L)Cl2] and [M(L)2Cl2]. Electronic spectral data and magnetic measurements showed that some of the complexes have octahedral geometry while the other complexes have tetrahedral geometry.
