Under solvothermal conditions, using Ni(NO₃)₂·6H₂O as the metal source, pentamethy lisophthalic acid (H₂MIP) ligand and 1,3-bis(2-methyl-1H-imidazol-1-yl)propane (BMIP) as mixed ligands, a new Ni(Ⅱ) organic framework material, {[Ni₄(MIP)₄(BMIP)₃]·DMF}_n (SNUT-36), was constructed. X-ray single crystal diffraction analysis shows that SNUT-36 presents a binodal (4,6) connected double-interpenetrated three-dimensional skeleton structure with topological analysis data of (3²·4⁵·5·6⁷)(3⁴·4⁷·5·6³). The obtained complex was further characterized by powder X-ray diffraction, infrared spectroscopy, thermogravimetric analysis and other means. In addition, the electrochemical test results show that SNUT-36 achieve an overpotential of 430 mV at 20 mA·cm^-2, indicating its good electrocatalytic performance. The Tafel slope of 89 mV·dec^-1 also confirmed its good effect on improving the oxygen evolution reaction rate.
