Hydrothermal reaction of a macrocyclic inorganic POM cavitand Li(NH)H[PWO] with [Pt(HO)(OH)] results in coordination of up to six {Pt(HO)(OH)} fragments to the internal surface of the polyoxoanion. The product was isolated as K(NH)H[{Pt(OH)(HO)}PWO]·79HO () and characterized by multiple techniques in the solid state (SCXRD, XRPD, XPS, FTIR, and TGA) and in solution (NMR, ESI-MS, and HPLC-ICP-AES). Electrochemical properties were studied both in solution and as components of the paste electrode. The complex shows electrocatalytic activity in water oxidation.
大环无机多金属氧酸盐空穴配体Li(NH)H[PWO]与[Pt(HO)(OH)]的水热反应导致多达六个{Pt(HO)(OH)}片段配位到多氧阴离子的内表面。产物以K(NH)H[{Pt(OH)(HO)}PWO]·79HO ()形式分离出来，并通过多种固态技术（单晶X射线衍射、X射线粉末衍射、X射线光电子能谱、傅里叶变换红外光谱和热重分析）以及溶液技术（核磁共振、电喷雾电离质谱和高效液相色谱-电感耦合等离子体发射光谱）进行表征。研究了该配合物在溶液中和作为糊状电极组分时的电化学性质。该配合物在水氧化中表现出电催化活性。
