Synthesis, characterization, spectral and thermal properties of metal-hydrazinium nitrilotriacetates

Hydrazine derivatives of the monobasic nitrilotriacetate salts of zinc and alkaline earth metals have been prepared. IR absorption frequencies and thermal properties of these metal-hydrazinium nitrilotriacetates, (N2H5)M[N(CH2COO)(3)]. xH(2)O have been defined. All the three -COOH appear to be dissociated in these salts. In thermal decomposition, these salts initially undergo dehydration followed by dehydrazination and via acetate intermediate step to metal oxycarbonates.
