Abstract EN
Metal complexes ([ML2], where M =Fe, Co, or Zn; HL =2-[(6-ethyl-5-oxo-4,5-dihy dro-2H-[1,2,4]triazin-3-ylidene)-hydrazono]-butyric acid, C9H13N5O3) of a Schiff base derived from a-ketobutyric acid (a-KBA) and diaminoguanidine (Damgu) were synthesized and characterized using elemental, spectral, and thermal studies.
The metal complexes exhibited similar decomposition behavior, with a highly exothermic final decomposition step resulting in the formation of metal oxides.
Isomorphism among the complexes was revealed using a powder X-ray diffraction (PXRD) technique.
Solid solution precursors ([Zn1/3M2/3(L)2], where M= Fe, Co) were synthesized and characterized using various physico-chemical techniques.
A thermal decomposition technique was used to prepare spinel-type zinc cobaltite (ZnCo2O4) and zinc ferrite (ZnFe2O4) nanocrystalline particles with the synthesized single source precursors.
Structural studies using PXRD ascertained the predominant crystal phase to be spinel.
Transmission electron microscopy (TEM) and highresolution TEM (HRTEM) showed a mean nanoparticle size of 18 ±2 nm.
Magnetic measurements revealed a weak magnetic behavior in the synthesized spinels.
In the aqueous phase, the spinels exhibited catalytic activity, reducing 4-nitrophenol (4-NP) in the presence of NaBH4 at room
