The coordination geometry of each Co atom is formed, by two N atoms from two benzyl-benzimidazole ligands and by two Cl anions, is of a tetrahedron. The data of EA, IR and UV-vis spectra are in good agreement with the result of crystal structure determination. The thermal gravimetry (TG) data indicate that there are four decomposition steps with five endothermic peaks. The final product of the thermal decomposition is Co. The electrochemical properties of the complex was also studied in H2O/DMF solvent by cyclic voltammetry(CV). CCDC:211442.展开更多
