Abstract

We have prepared the three novel Pd(II)-containing tungstophosphates Pd(2)(α-PW(11)O(39)H(0.5))(2) and two structural isomers of Pd(2)(α(2)-P(2)W(17)O(61)H(n))(2) via simple synthetic procedures and characterized their potassium salts by single-crystal X-ray diffraction, elemental analysis, and IR and multinuclear ((31)P and (183)W) NMR spectroscopy. This study sheds light on the long-standing question about the nature and structure of the actual products formed in the reaction of Pd(II) ions with monolacunary Keggin-type α-XW(11)O(39) and Wells-Dawson-type α(2)-P(2)W(17)O(61) heteropolytungstates.

摘要

我们通过简单的合成程序制备了三种新型的含钯（II）的磷钨酸盐Pd(2)(α-PW(11)O(39)H(0.5))(2)和Pd(2)(α(2)-P(2)W(17)O(61)H(n))(2)的两种结构异构体，并通过单晶 X 射线衍射、元素分析以及红外和多核((31)P 和 (183)W)NMR 光谱对其钾盐进行了表征。这项研究阐明了关于 Pd(II)离子与单缺位 Keggin 型α-XW(11)O(39)和 Wells-Dawson 型α(2)-P(2)W(17)O(61)杂多钨酸盐反应中实际产物的性质和结构的长期存在的问题。
