Biomimetic complexes of Co(II), Cu(II) and Ni(II) with 2-aminomethylbenzimidazole. EGA-MS characterization of the thermally induced decomposition

Substituted benzimidazoles are a useful model ligand to simulate specific interactions in biomimetic complexes, since compounds that contain the imidazole ring of the histidine residue are good models of bioinorganic interest. In this study, Co(II), Cu(II) and Ni(II) complexes with 2-aminomethylbenzimidazole ligand, synthesized following the literature, were characterized by mass spectrometry evolved gas analysis (EGA-MS) that allowed one to describe their thermally induced decomposition. © 2014 Elsevier B.V
