| Abstract: | N,N'-Diphenyldithiomalonamide, (C6H6. NH. CS)2CH2, is found to be a very suitable gravimetric reagent for nickel(II) and cobalt(II). The complexes, of composition Ni(C15H13N2S2)2 and Co(C15H13N2S2)3, are stable and can be weighed after drying at 110°. Separation from base metals has been studied, and the structural interpretation is supported by DTA, TG, infrared and NMR data. |
