Hydrothermal Syntheses,Crystal Structures,TGA and Electrochemistry Properties of Two Metal-organic Coordination Compounds Based on 4'-((1H-1,2,4-triazol-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitril

Two novel metal-organic coordination compounds with molecular structures of {[Co(TMBC)4Cl2]·2H2O}(1) and {[Ni(TMBC)4Cl2]·2H2O}(2)(TMBC = 4'-((1H-1,2,4-triazol-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile), have been synthesized under hydrothermal conditions of Co Cl2·6H2O and Ni Cl2·6H2O with 4'-((1H-1,2,4-triazol-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile, respectively. Both compounds crystallize in triclinic systems, space group P 1. They are characterized by single-crystal X-ray diffraction analysis, elemental analysis, IR spectroscopy and TGA. Moreover, their electrochemical behaviors have also been studied in different electrolyte solutions, respectively.
