“…In 1952, the first biological activity of cobalt compounds was acquainted where cobalt(III) compounds of bidentate mustard move as if it were hypoxia selective agents. Then, some compounds demonstrated significant activity against bacterial strains and against leukemia and lymphoma cell lines [20]. Afterward, lots of studies were carried out on anti-microbial, anti-fungal and anti-oxidant activities of cobalt compounds [16].…”

This chapter aims to collect and summarize the chemical properties of cobalt and some new cobalt compounds. It deals with the progress of cobalt chemistry. Cobalt has been substantial in both chemical reactions and within many compounds. Some of them are heterocyclic reactions, cobalt-based catalyst and cobalamin. Also, it discusses variety of applications of cobalt in a wide range of areas and toxicity of cobalt. The studies carried out in this area so far have enabled and will be continued to be responsible for producing unknown and difficult reactions. This survey of the recent literature illustrates the fact that many different approaches on cobalt and new cobalt compounds are being used in many different areas.

“…Interest in exploring benzimidazole derivatives and their metal complexes has continually increased, since many of these materials may serve as models which mimic both the structure and reactivity of metal ion sites in complex biological systems [20][21][22][23][24][25][26][27]. Sandoval et al studied the synthesis, structure and biological activities of zinc(II) coordination compound with 2-benzimidazole derivatives [24].…”

“…Guadarrama et al studied the cytotoxic activity, X-ray crystal structures and spectroscopic characterization of cobalt(II), copper(II) and zinc(II) coordination compounds with 2-substituted benzimidazoles [27]. To the best of our knowledge, the study of the electrochemistry and electrocatalysis of zinc complexes containing benzimidazole are less reported [24][25][26][27]. The significance of this work is that it uses a new zinc complex [Zn(C 3 H 7 -bim) 2 Br 2 ] as a bulk-modifier, to fabricate a chemically modified carbon paste electrode monochromator.…”

Abstract:The present work reports the synthesis, characterization and performance of a new zinc(II) complex of [Zn(C 3 H 7 -bim) 2 Br 2 ] (bim = benzimidazole) as electrocatalyst for trichloroacetic acid and bromate reduction. Its structure was characterized by X-ray crystallography, IR spectroscopy and elemental analysis. The zinc atom adopts a distorted tetrahedral geometry by coordinating to two bromine atoms and two nitrogen atoms from two 1-propyl-1H-benzo[d]imidazole ligands. The electrochemical behavior and electrocatalysis of the zinc complex bulk-modified carbon paste electrode (Zn-CPE) have been studied by cyclic voltammetry. The Zn-CPE shows good electrocatalytic activities toward the reduction of trichloroacetic acid and bromate. The detection limit and the sensitivity are 0.05 μM, 67.43 μA μM -1 for trichloroacetic acid detection, and 0.02 μM, 69.94 μA μM -1 for bromate detection, respectively. This modified electrode shows good reproducibility, high stability, low detection limit, technical simplicity and possibility of rapid preparation, which is important for practical applications.
