Abstract A new inorganic–organic hybrid 22-Ni-substituted phosphotungstate, [Ni(H2O)2(en)]2[Ni(H2O)(en)2]2{[Ni6(OH)2(H2O)(en)2(B-α-PW9O34)]2[W4O16][Ni5(H2O)3(en)3(PW6O26)]2}·24H2O (1, en = ethylenediamine) has been made by hydrothermal method and characterized by elemental analysis, single crystal X-ray diffraction, powder X-ray diffraction, IR spectroscopy, thermogravimetric analysis, and UV–Vis diffuse-reflectance spectroscopy, respectively. Compound 1 contains a 22-Ni-substituted polyoxoanion built by central [W4O16]8− core and two different symmetrical clusters, [Ni6(OH)2(H2O)(en)2(B-α-PW9O34)]+ and [Ni5(H2O)3(en)3(PW6O26)]−, which is further linked by double-bridging [Ni(H2O)2(en)]2+ cations to form 1-D chain. Moreover, the counter cations, [Ni(H2O)(en)2]2+ support to the [B-α-PW9O34]9− fragments.

一种新的 22-Ni 取代的多金属氧酸盐：水热合成、结构和电化学性能

摘要 一种新的无机-有机杂化 22-Ni 取代磷钨酸盐，[Ni(H2O)2(en)]2[Ni(H2O)(en)2]2{[Ni6(OH)2(H2O)(en)2 (B-α-PW9O34)]2[W4O16][Ni5(H2O)3(en)3(PW6O26)]2}·24H2O (1, en = 乙二胺) 已采用水热法制备并经元素分析表征，单分别采用晶体 X 射线衍射、粉末 X 射线衍射、红外光谱、热重分析和紫外-可见漫反射光谱。化合物 1 包含由中心 [W4O16]8− 核心和两个不同的对称簇构建的 22-Ni 取代的多氧阴离子，[Ni6(OH)2(H2O)(en)2(B-α-PW9O34)]+ 和 [Ni5 (H2O)3(en)3(PW6O26)]-，通过双桥连 [Ni(H2O)2(en)]2+ 阳离子进一步连接形成一维链。此外，抗衡阳离子 [Ni(H2O)(en)2]2+ 支持 [B-α-PW9O34]9- 片段。
