表现出长程磁序的材料是信息存储和电子工业的同义词，这种现象通常与金属、金属合金或金属氧化物和硫化物有关。一类不太为人所知的磁性有序化合物是高度各向异性的d-块过渡金属的单金属化合物；从孤立的零维分子到有序的、自旋倾斜的三维晶格的‘转变’是通过空间相互作用的结果，这些相互作用是由于大的磁各向异性和从金属到配体的自旋离域的结合而引起的，这导致了重要的分子间接触。在这里，我们报道了压力对两个这样的单核Re(IV)化合物的影响，它们在环境条件下通过自旋倾斜机制显示出长程磁序，T_c由分子间相互作用的强度控制。由于它们是由分子间的距离决定的，将分子挤压得更近会产生显著的有序化温度增强，T_c与压力成线性关系。展示长程磁序的材料是信息存储的同义词。本文报道了压力对两种单核Re化合物的影响，这两种化合物在环境条件下通过自旋倾斜机制表现出长程磁序，其中Tc与压力成正比。
Materials that demonstrate long-range magnetic order are synonymous with information storage and the electronics industry, with the phenomenon commonly associated with metals, metal alloys or metal oxides and sulfides. A lesser known family of magnetically ordered complexes are the monometallic compounds of highly anisotropic d-block transition metals; the ‘transformation' from isolated zero-dimensional molecule to ordered, spin-canted, three-dimensional lattice being the result of through-space interactions arising from the combination of large magnetic anisotropy and spin-delocalization from metal to ligand which induces important intermolecular contacts. Here we report the effect of pressure on two such mononuclear rhenium(IV) compounds that exhibit long-range magnetic order under ambient conditions via a spin canting mechanism, with Tc controlled by the strength of the intermolecular interactions. As these are determined by intermolecular distance, ‘squeezing' the molecules closer together generates remarkable enhancements in ordering temperatures, with a linear dependence of Tc with pressure. Materials that demonstrate long-range magnetic order are synonymous with information storage. Here, the authors report the effect of pressure on two mononuclear rhenium compounds that exhibit long-range magnetic order under ambient conditions via a spin canting mechanism, where T c is proportional to pressure.
