Abstract

Three novel heteropolyanions [PMo(12)Sb(2)O(40)][Cu(enMe)(2)].4H(2)O (), [PMo(12)Sb(2)O(40)][Ni(enMe)(2)].4H(2)O (2) and [PMo(12)Sb(2)O(40)][Cu(en)(2)].H(3)O.H(2)O (3) (enMe = 1,2-diaminopropane, en = ethylene diamine) have been synthesized and characterized by IR spectroscopy, X-ray photoelectron spectroscopy (XPS), thermogravimetric analyses and elemental analyses. Single-crystal X-ray diffraction analyses reveal that these three compounds represent the first examples of compounds based on the novel polyoxoanion {PMo(12)Sb(2)O(40)} and different transition metal coordination complexes. 1 and 2 are isostructural and both exhibit novel 1-D structures. In contrast to 1 and 2, 3 exhibits a substantially distinct novel 1-D structure. In addition, 3 is the first example of an extended structure constructed from polyoxoanions and Cu(+) transition metal coordination complexes.

摘要

三种新型杂多阴离子[PMo(12)Sb(2)O(40)][Cu(enMe)(2)].4H(2)O (), [PMo(12)Sb(2)O(40)][Ni(enMe)(2)].4H(2)O (2) 和 [PMo(12)Sb(2)O(40)][Cu(en)(2)].H(3)O.H(2)O (3) (enMe = 1,2-二氨基丙烷，en = 乙二胺)已通过红外光谱、X 射线光电子能谱 (XPS)、热重分析和元素分析进行了合成和表征。单晶 X 射线衍射分析表明，这三种化合物代表了基于新型多氧阴离子{PMo(12)Sb(2)O(40)}和不同过渡金属配位络合物的化合物的第一个例子。1 和 2 是同构的，均呈现新颖的 1-D 结构。与 1 和 2 不同，3 呈现出截然不同的新颖 1-D 结构。此外，3 是由多氧阴离子和 Cu(+)过渡金属配位络合物构建的扩展结构的第一个例子。
