In this collaborative project, crystalline phases based on anion-radicals of endohedral metallofullerenes (EMFs) will be prepared and thoroughly characterized by structure determination methods, spectroscopy, powder and single-crystal magnetometry, as well as quantum-chemical calculations. Structural studies of the crystals formed from EMF anion radicals will clarify the mechanisms of the electron transfer exhibited by EMFs in solution. Synthesis of the anionic solids of EMFs targeted in this project will lead to a new class of materials with unprecedented electronic and magnetic properties. Intermolecular interactions of fullerene-based anion-radicals in such crystals will lead to a variety of magnetic phenomena, as it was already demonstrated for empty fullerenes. At the same time, electronic charging magnetic lanthanide-based EMFs will modify the intra- and intermolecular magnetic coupling between lanthanide ions and reinforce single molecule magnetism exhibited by such EMFs.

在这个合作项目中，将制备基于阴离子自由基的内源性金属富勒烯（EMFs）晶体相，并通过结构测定方法、光谱学、粉末和单晶磁强计以及量子化学计算对其进行全面表征。电动势阴离子自由基形成晶体的结构研究将阐明电动势在溶液中电子转移的机制。该项目所针对的阴离子固体电磁场的合成将导致一类具有前所未有的电子和磁性能的新材料。在这种晶体中，基于富勒烯的阴离子自由基的分子间相互作用将导致各种各样的磁性现象，正如空富勒烯已经证明的那样。同时，电子充电磁性镧系emf将改变镧系离子之间的分子内和分子间的磁耦合，并增强这种emf所表现出的单分子磁性。
