Three dimensional mixed ligand supramolecular and electrochemical property based on hydrogen bond

The complex [Co(H2O)6]·[Co(phen)2(H2O)2]2·(BTC)2·24.6H2O(H3BTC=benzene-1,3,5-tricarboxylic acid,phen =1,10-phenanthroline)was synthesized by the hydrothermal reaction and characterized by single crystal X-ray diffraction analysis,element analysis,TGA,and infrared spectrum.The result shows that the crystal structure belongs to monoclinic system,space group P2(1)/c.The asymmetrical structure unit of the crystal consists of one benzene-1,3,5-tricarboxylic acid ion and two six-coordinational metal Co(Ⅱ) centers,which locate in octahedron MN2O4 and MO6,respectively forming two mononuclear cations [Co(H2O)6]2+ and [Co(Phen)2(H2O)2]2+.The three isolated structure are linked further by hydrogen bonds(O—H…O) to three dimensional supremolecular structure.The cyclic volatmmetric behavior of the complex was also investigated for the definition of the identity of the couple of redox peaks.
