In this Communication, we illustrate the influence of organic ligands on magnetic structure and behavior by employing a mixed-valence Lindqvist-type hexavanadate as a research platform. Through covalently attaching to different halogen-containing organic ligands, the derived hybrid materials have different magnetism compared to their parent structure. Single-crystal X-ray analyses show that the introduction of organic ligands can modify the crystal packing manners of the derivatives, leading to further changes of the interaction between magnetic units. This work demonstrates that organic functionalization can remarkably affect the magnetism of polyoxometalates by adjusting the distance and location of the magnetic fractions.
在本通讯中，我们以一种混合价态的Lindqvist型六钒酸盐作为研究平台，阐述了有机配体对磁性结构和行为的影响。通过共价连接不同的含卤有机配体，所得到的杂化材料与其母体结构相比具有不同的磁性。单晶X射线分析表明，有机配体的引入可以改变衍生物的晶体堆积方式，进而导致磁性单元之间相互作用的进一步变化。这项工作表明，有机官能化可以通过调整磁性组分的距离和位置，显著影响多金属氧酸盐的磁性。
