试试看，只能说试试看～～～ Two New One-Dimensional Chain-Like Compounds Constructed from the Sandwich-Type Polyoxotungstate Clusters由多层式多金属钨酸盐簇合成的两种新型类尺寸链结构复合物Introduction 简介Polyoxometalates (POMs), as metal–oxygen cluster ions, have been attracting extensive interests due to their enormous structural varieties and the accompanying multitude of potential applications in the field of catalysis, electrochemistry, electrochromism and magnetism [1, 2]. 多金属氧酸盐，也就是金属-氧簇离子簇，一直以来都因为它们巨大的结构多样性，以及由此产生其在催化，电化学，电变色和磁化领域的应用潜能引发研究者的广泛关注[1, 2]。The evolution of POM chemistry is dependent upon the synthesis of novel polyoxoanions possessing unique structures and physicochemical versatilities. With the aim of producing novel polyoxoanions, much attention has focused on the self-assembly of preformed building units.多金属氧酸盐化学的进展依赖于新型多聚阴离子簇工艺的独特结构和物理化学普适性。在制备新型多聚阴离子簇方面，大量的注意力都集中在预成型合成单元的自我合成。 In this subfamily, lacunary POMs represent one of the excellent inorganic precursors to construct new compounds with diverse nuclearities and structural features combined with interesting catalytic, electrochemical and magnetic properties, which have attracted considerable attention worldwidely [3]. 在这个子课题下，多空隙的多金属氧酸盐代表了一种优良的非有机前驱材料，其合成的新型复合物具备多核性（???）以及令人感兴趣的包括催化，电化学和磁化特性，这类复合物已经在世界范围内引发重大关注[3]。Up to now, numerous sandwich- type polyoxoanions have been synthesized by the reactions of the lacunary polyoxoanions with the transition metal cations, and mostly belong to the well-known Weakley-, Herve′-, Krebs- and Knoth-type sandwich structures [4, 5]. 至今，已有大量多层式多聚阴离子簇通过多空隙阴离子簇与过渡金属反应合成，其中大多数属于广为人知的威克利，赫维，克雷布斯和克努斯多层结构 [4, 5]。They each accommodated a paramagnetic transition metal-set between two lacunary polyoxoanions, which make them exhibit interesting catalytic, magnetic, electrochemical properties. 这些结构各自都在两种多空隙多聚阴离子簇之间设置顺磁性过渡金属键合，使其呈现令人感兴趣的催化，磁化以及电化学特性。It is known to all that the sandwich-type polyoxoanions have a larger volume and a more-negative charge than that of the commonly used polyoxovanadate/-molybdate in constructing the extended structure materials, which allow the formation of higher coordination numbers with transition-metal cations. 正是因为多层式多聚阴离子簇能够形成更高的与过渡金属反应的配位数，在合成延展结构材料方面它们能提供比一般使用的多聚钒酸盐或者多聚钼酸盐更多的电负性更强的电荷。These sandwich-type clusters should be the excellent precursors, but are used scarcely for constructing the extended structure materials [6]. 这类多层式簇离子簇将会是优良的前驱材料，但目前在合成延展结构材料方面的应用却极为少见 [6]。In this article, we reported two new one dimensional chain-like compounds constructed from the M4-sandwiched polyoxoanions. 本文将提出由M4多层多聚阴离子簇合成的两种新型类尺寸链结构复合物。Materials and Methods 材料与方法All chemicals were commercially purchased and used without further purification. 所有化学品都从市场购买并未做进一步纯化。 K8[b-GeW11O39] 14H2O and K8[c-SiW10O36] 12H2O were synthesized according to the literatures [7] and characterized by IR spectra.
