Abstract A new Ni11-cluster sandwiched phosphotungstate supported by Ni(H2O)5 group H2[Ni(H2O)6]{[Ni11(OH)6(H2O)(en)2(Hen)2(L)3](PW9O34)2[Ni- (H2O)5]}·20H2O (1, en = 1,2-ethylenediamine, L = iminodiacetate), has been made under hydrothermal conditions and characterized by IR spectrum, thermogravimetric analysis, elemental analysis, single-crystal X-ray diffraction and powder X-ray diffraction, respectively. The structure analysis reveals that 1 contains the Ni11-cluster sandwiched polyoxoanion {[Ni11(OH)6(H2O)(en)2(Hen)2-(L)3](PW9O34)2}6-, which is further linked each other via N–H···O H-bond interactions to form a zigzag chain. UV-Vis spectrum reveals that 1 is a wide-gap semiconductor. Electrochemical behavior of 1 illustrated that the three pairs of redox peaks attributed to the redox process of the WVI centers.

摘要 一种由 Ni(H2O)5 基团 H2[Ni(H2O)6]{[Ni11(OH)6(H2O)(en)2(Hen)2(L)3](PW9O34)支撑的新型 Ni11 簇夹层磷钨酸盐2[Ni- (H2O)5]}·20H2O (1, en = 1,2-乙二胺, L = 亚氨基二乙酸酯), 水热条件下制备, 红外光谱, 热重分析, 元素分析, 单晶X分别为 - 射线衍射和粉末 X 射线衍射。结构分析表明，1含有Ni11-cluster夹杂多氧阴离子{[Ni11(OH)6(H2O)(en)2(Hen)2-(L)3](PW9O34)2}6-，其进一步连接每个其他通过 N-H···O 氢键相互作用形成锯齿链。UV-Vis 光谱表明 1 是一种宽禁带半导体。1 的电化学行为表明三对氧化还原峰归因于 WVI 中心的氧化还原过程。
