摘要：

The tris dithioacetato complexes of chromium(III), iron(III), cobalt(III) and rhodium(III) have been prepared and characterized through magnetic susceptibility measurements, IR, electronic, NMR and ESR spectroscopy. Cr(dta)3 has a temperature independent μeff = 3.86 BM and g = 1.9887. The iron complex is low spin with μeff = 2.00-2.20 BM, in the range 93-293 K, and, at 105 K, shows g1 = 2.152, g2 = 2.097, g3 = 2.009. These data and the ligand field parameters derived from the electronic spectra are indicative of appreciable metal-ligand covalency. The properties of the complexes are compared with those of the corresponding dithiobenzoates, dithiocarbamates and xanthates. © 1979.
