Synthesis, TG, DSC and infrared spectral study of NiMn2(C4H4O4)3·6N2H4

Nickel manganese succinato-hydrazinate (NiMn₂(C₄H₄O₄)₃·6N₂H₄), has been synthesized for the first time by a novel precursor technique and characterized by IR, AAS and XRD. Thermal decomposition of the compound was studied from room temperature (rT) to 800°C by differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis besides isothermal mass loss studies. The compound was found to decompose autocatalytically, once ignited. TG-DSC shows two steps decomposition i.e. dehydrazination followed by decarboxylation. The infrared spectral studies show the N–N stretching frequency at 972 cm^–1 suggesting a bidentate bridging structure of hydrazine molecule in (NiMn₂(C₄H₄O₄)₃·6N₂H₄).
