Biomimetic complexes of Co(II), Mn(II), and Ni(II) with 2-propyl-4,5-imidazoledicarboxylic acid. EGA-MS characterization of the thermally induced decomposition

Solid complexes of Co(II), Mn(II), and Ni(II) with 2-propyl-4,5-imidazoledicarboxylic acid have been prepared and studied by means of mass spectrometry evolved gas analysis (EGA-MS). The applied hyphenated thermoanalytical approach has allowed description of the thermally induced decomposition steps and has supported the suggested mechanism. The results of this work in combination with the earlier reported data have suggested that two main thermally induced decomposition pathways are common of the imidazole-substituted complexes.
