Transition-metal bimaleates and their solid solutions: Synthesis, structural, and thermoanalytical study
摘要:
Transition-metal hydrogen maleates of composition M(C4H3O4)(2) center dot 4H(2)O, where M = Mn, Fe, Co, and Ni, and their solid solutions were synthesized and characterized by X-ray crystallography, IR spectroscopy, mass spectrometry, and thermal analysis. X-ray crystallography and IR spectroscopy showed that both intramolecular and intermolecular H-bonds exist in these compounds. The generation of continuous substitutional solid solutions with cation substitution in these compounds was studied. The thermolysis mechanism was studied for both transition-metal hydrogen maleates and their solid solutions. The composite produced by thermolysis is stable up to 1200 degrees C in flowing helium.
