The synthesis and properties of Tris(dithioacetylacetonato) complexes of cobalt(III), rhodium(III), and iridium(III)

Abstract

.The syntheses of the cobalt(III), rhodium(III), and iridium(III) complexes of dithioacetylacetone, [M(SacSac)₃], are described. The tris-chelates are neutral dia- magnetic monomers. Infrared, proton magnetic resonance, and electronic spectra are reported. Polarography in acetone shows that these complexes are reduced at more negative potentials than those of the iron(III) group. Various related complexes [Co(SacSac)₂(X-Y)] have also been prepared.
