Synthesis, characterization and thermal behaviour of solid-state compounds of folates with some bivalent transition metals ions

摘要

Solid-state M–L compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and L is folate (C_(19)H_(17)N_7O_6), have been synthesized. Simultaneous thermogravimetry and differential scanning calorimetry (TG– DSC), X-ray powder diffractometry, infrared spectroscopy (FTIR), TG–DSC coupled to FTIR, elemental analysis and high-resolution continuum source flame atomic absorption spectrometry technique (HR-CS FAAS) were used to characterize and to study the thermal behaviour of these compounds. The results provided information concerning the composition, dehydration, thermal stability and thermal decomposition.
