Abstract:
We report on the synthesis of new manganese carbonyls-based materials prepared using gamma-rays radiation (at doses of 10 and 40 kGy) as energy source. Characterization was achieved using nuclear magnetic resonance, infrared spectroscopy, elemental analysis, single-crystal X-ray diffraction, differential scan calorimetry, thermogravimetric analysis, and mass spectrometry. The irradiated materials presented enhanced thermal stability along with formation of spherical shaped microparticles sized around 0.95 μm attested by scanning electron microscopy and energy-dispersive X-ray spectroscopy.
