Abstract

A d¹⁰-Cd cluster containing sandwich-type arsenotungstate [C₃H₁₂N₂]₆[Cd₄Cl₂(B-α-AsW₉O₃₄)₂] was synthesized and its structure characterized through elemental analyses, X-ray powder diffraction (XRPD), IR spectroscopy, X-ray photoelectron spectroscopy (XPS), and single-crystal X-ray diffraction. The X-ray analysis revealed that the molecular unit of the compound consists of a captivating tetra-Cd-substituted sandwich-type polyoxoanion, accompanied by six elegantly protonated 1,2-diaminopropane as counter ions. The further novelty of the tetranuclear cadmium cluster lies in its occupied chlorine atom sites. This makes it highly susceptible to coordinate reactions with nitrogen on polycyclic aromatic hydrocarbons, thereby exhibiting different fluorescent signals that facilitate the identification and detection of these carcinogenic substances in methanol.

含 d10-Cd 簇的夹心型胂钨酸盐在甲醇中能荧光识别致癌染料。

通过元素分析、X 射线粉末衍射 (XRPD)、红外光谱、X 射线光电子能谱 (XPS) 和单晶 X 射线衍射，合成了含有 d10-Cd 簇的夹心型砷钨酸盐 [C3H12N2]6[Cd4Cl2(B-α-AsW9O34)2]，并对其结构进行了表征。X 射线分析表明，该化合物的分子单元由一个迷人的四镉取代夹心型多氧阴离子和六个优雅的质子化 1,2 二氨基丙烷作为反离子组成。四核镉簇的另一个新颖之处在于其占据的氯原子位点。这使得它极易与多环芳香烃上的氮发生配位反应，从而显示出不同的荧光信号，有助于在甲醇中识别和检测这些致癌物质。

期刊介绍： Molecules (ISSN 1420-3049, CODEN: MOLEFW) is an open access journal of synthetic organic chemistry and natural product chemistry. All articles are peer-reviewed and published continously upon acceptance. Molecules is published by MDPI, Basel, Switzerland. Our aim is to encourage chemists to publish as much as possible their experimental detail, particularly synthetic procedures and characterization information. There is no restriction on the length of the experimental section. In addition, availability of compound samples is published and considered as important information. Authors are encouraged to register or deposit their chemical samples through the non-profit international organization Molecular Diversity Preservation International (MDPI). Molecules has been launched in 1996 to preserve and exploit molecular diversity of both, chemical information and chemical substances.
