Five new organic-inorganic hybrid compounds based on [PWO] (abbreviated as {PW}) and several types of transition metal complexes (TMCs) have been synthesized and characterized by IR, UV-Vis, XRD, cyclic voltammetry measurements and single crystal X-ray diffraction analysis. [Cu(phen)][Cu(phen)(HO)][Cu(phen)(HO)][PWO]·8HO (1) (phen = 1,10-phenanthroline) is a {PW} bi-supported complex of phen, while [Cu(2,2'-bpy)(HO)][Cu(2,2'-bpy)][PWO]·3.5HO (2) (2,2'-bpy = 2,2'-bipyridine) is a 1-D chain structure formed by {PW} and copper complexes of 2,2'-bpy. [Ag(2,2'-bpy)][HPWO]·HO (3), [Ag(2,2'-bpy)(HO)][Ag(2,2'-bpy)][Ag(2,2'-bpy)][PWO] (4), and [Ag(2,2'-bpy)(HO)][Ag(2,2'-bpy)][Ag(2,2'-bpy)][PWO]·HO (5) are constructed from {PW} and silver complexes of 2,2'-bpy. Compounds 4 and 5 are novel dimers of {PW} joined by silver complexes, while compound 3 contains two different kinds of silver complexes, forming a novel supramolecular structure. Each of the five compounds is formed by {PW} and more than one type of TMC. The formation mechanism of these compounds has been carefully discussed. In addition, we also synthesized two supramolecular structures based on {PW} and organic moieties: HPWO (6) and HPWO·43HO (7). The catalytic properties of these compounds were also tested.
已经合成了五种基于[PWO]（简称为{PW}）和几种过渡金属配合物（TMCs）的新型有机-无机杂化化合物，并通过红外光谱（IR）、紫外-可见光谱（UV-Vis）、X射线衍射（XRD）、循环伏安测量和单晶X射线衍射分析对其进行了表征。[Cu(phen)][Cu(phen)(H₂O)][Cu(phen)(H₂O)][PWO]·8H₂O (1)（phen = 1,10-菲咯啉）是一种{PW}双支撑的菲咯啉配合物，而[Cu(2,2'-bpy)(H₂O)][Cu(2,2'-bpy)][PWO]·3.5H₂O (2)（2,2'-bpy = 2,2'-联吡啶）是由{PW}和2,2'-联吡啶的铜配合物形成的一维链状结构。[Ag(2,2'-bpy)][H₂PWO]·H₂O (3)、[Ag(2,2'-bpy)(H₂O)][Ag(2,2'-bpy)][Ag(2,2'-bpy)][PWO] (4)和[Ag(2,2'-bpy)(H₂O)][Ag(2,2'-bpy)][Ag(2,2'-bpy)][PWO]·H₂O (5)是由{PW}和2,2'-联吡啶银配合物构建而成。化合物4和5是通过银配合物连接的{PW}新型二聚体，而化合物3包含两种不同类型的银配合物，形成了一种新型超分子结构。这五种化合物中的每一种都是由{PW}和不止一种类型的TMC形成的。已经仔细讨论了这些化合物的形成机制。此外，我们还合成了两种基于{PW}和有机部分的超分子结构：H₂PWO (6)和H₂PWO·43H₂O (7)。还测试了这些化合物的催化性能。
