Hydrazinium rare earth metal

Hydrazinium Rare Earth Metal Sulfate Hydrates-N2H5Ln(S04)2-H20... [Pg.179]

A hot aqueous solution of lanthanide sulfate hydrate, Ln2(S04)3- H20 (where Ln = La, Ce, Pr, Nd, or Sm), taken in H2SO4 is mixed with (N2H5)2S04 or N2H6SO4. The resulting solution when left to stand in air affords the respective hydrazinium rare earth metal sulfate [19]. Small crystals suitable for X-ray studies are obtained in a few days. They exhibit the characteristic color of the lanthanide ions ... [Pg.179]
