Modeling Spin Interactions in a Triangular Cobalt(II) Complex with Triaminoguanidine Ligand Framework: Synthesis, Structure, and Magnetic Properties

“…Polynuclear complexes of paramagnetic metal ions are continuously attracting considerable attention, not only due to their intriguing structures and magnetic properties but also due to their potential application in functional molecule-based materials. − The discovery of single-molecule magnets (SMMs) and their potential applications in high-density information storage has immensely stimulated the investigation of metal complexes in search of SMMs with high blocking temperature and slow magnetization relaxation. , This has particularly led to the discovery of a series of cobalt-based oligonuclear complexes exhibiting SMM behavior. , Besides this high-nuclearity approach recent years have shown that even mononuclear metal complexes provide a basis for systems exhibiting slow magnetic relaxation. − Also within this new class of single-ion magnets (SIMs) cobalt­(II) high-spin complexes with their S = 3/2 half-integer spin state attracted increasing interest in the past few years. − Toward the investigation of the electronic structure of such cobalt­(II)-based systems various spectroscopic methods have been employed such as multifrequency, high-field ESR, and variable-temperature, variable-field magnetic circular dichroism (MCD). − In this context the magnetic properties of polynuclear cobalt­(II) complexes have also been of general interest, and along this line numerous dinuclear, − trinuclear, − …”

“…Very similarly, an unsuccessful result was obtained with the function from ref.,33 in which a crystal‐field effect is considered in addition to the interaction between Co II ions (– JS 1 S 2 ). However, we were still unable to describe adequately the increase of the susceptibility below 14 K.…”
