N,N'-diphenyldithiomalonamide as a gravimetric reagent for nickel and cobalt.
N,N'-Diphenyldithiomalonamide, (C(6)H(6). NH. CS)(2)CH(2), is found to be a very suitable gravimetric reagent for nickel(II) and cobalt(II). The complexes, of composition Ni(C(15)H(13)N(2)S(2))(2) and Co(C(15)H(13)N(2)S(2))(3), are stable and can be weighed after drying at 110 degrees . Separation from base metals has been studied, and the structural interpretation is supported by DTA, TG, infrared and NMR data.
