Magnetic materials have long been the subject of scientific inquiry. Nevertheless, the research started to expand its focus beyond aiming at low-dimensional systems. Exploring beyond the traditional bulk magnets could bring innovations thanks to different confinement resulting in unique physical properties. Apart from layer materials, molecular magnets are significant representatives. In this work, we are discussing an organo-metallic Cu(tn)Cl2 quantum magnet bearing a 2D layered magnetic structure. Combining DFT calculations with an evaluation of magnetic exchange interactions, we discuss the magnetic complex structure and show the strong dependence of the magnetic properties on molecular conformation. It includes not only the variation of the magnetic exchange but also the modification of the magnetic state itself.
Keywords: DFT; molecular magnets; exchange interactions
