A layered structural MOF [Ni(Hppza)₂]_n (1) was synthesized and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectroscopy. For complex 1, the crystal structure is extended into 3D structure through N–H···O hydrogen bond. And for the first time, this complex used as an electrode material for a supercapacitor. It exhibited large specific capacitance of 184 F g⁻¹ can be achieved at rates of 5 mV s⁻¹. The value demonstrated the best performance of all the MOF materials in supercapacitor at present. Such an excellent electrochemical property may be attributed to the intrinsic characteristics of Ni-MOF material including its crystal structure and morphology.

合成了层状结构的MOF [Ni（Hppza）₂ ] _n（1 ），并通过单晶X射线衍射，元素分析和红外光谱进行了表征。对于配合物1 ，晶体结构通过N·H··O氢键扩展为3D结构。并首次将此复合物用作超级电容器的电极材料。以5 mV s ^-1的速率可以实现184 F g ^-1的大比电容。该值是目前所有超级电容器中所有MOF材料的最佳性能。这种优异的电化学性能可归因于Ni-MOF材料的固有特性，包括其晶体结构和形态。
