Abstract: | Oxalates of La(III), Ce(III), Pr(III), Nd(III) and Sm(III) with the hydrazinium cation with the general formulae (N2H5)4Ln2(C2O4)57H2O (Ln=La3+, Ce3+, Pr3+) and N2H5Ln(C2O4)2·3.5H2O (Ln=Nd3+, Sm3+) were synthesized. The thermal decompositions of these compounds take place in three stages: thermal dehydration at 65–100°C, exothermic decomposition of the N2H4 at 230–260°C, and oxidation of the oxalate ion.This revised version was published online in November 2005 with corrections to the Cover Date. |
