通过水热合成了一种有机-无机杂化化合物[Ni4(3.Hpt)6(H2O)10Mo8O26]·Mo8O26·10H2O(3-Hpt=5-(3-吡啶基)-四唑),IR和X-射线单晶衍射实验测定和结构解析结果表明,该化合物是由双支撑形结构的[Ni4(3-Hpt)6(H2O)10Mo8O26]阳离子,卢构型[Mo8O26]簇阴离子及晶格水组成的。在阳离子中,卢构型[Mo8O26]簇通过中心对称的2个端基氧与2个双核配阳离子[Ni2(3-Hpt)3(H2O)5]^4+的镍原子配位形成双支撑形结构。将所得化合物制成碳糊电极(1-CPE),该电极在酸性水溶液中对亚硝酸根,溴酸根的还原有较好的催化活性。
An organic-inorganic hybrid compound [Ni4(3-Hpt)6(H2O)10Mo8O26]-Mo8O26· 10H2O (3-Hpt=5-(3-Pyridyl)- 1H-tetrazole has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction complex [Ni2(3-Hpt)3(H2O)5]4+ to from bisupporting polyoxometalate cations. A 3D supramolecular architecture is formed by hydrogen-bonding among the cations,anion and lattice water. Furthermore, the compound bulk-modified carbon-paste electrode (1-CPE) displays good electrocatalytic activity toward the reduction of NaBrO3 and NaNO2. CCDC: 943879.
