A Dy4 Cubane A New Member in the Single-Molecule Toroics Family
Abstract : Molecular materials that possess a toroidal moment associated to a non-magnetic ground state are known as Single-Molecule Toroics (SMTs) and are usually planar molecules. Herein, we report a Dy4 cubane, namely [Dy4(Bppd)4(µ3-OH)4(Pa)4(H2O)4]∙0.333H2O (where BppdH=1,3-Bis(pyridin-4-yl)propane-1,3-dione and PaH=2-Picolinic acid) for which magnetometry measurements and state-of-art ab initio calculations highlight SMT behavior in a tridimensional structure (3D-SMT). The in-depth theoretical analysis on the resulting low-lying energy states, along with their variation in function of the magnetic exchange pathways, allows to shed further light on the description of Single-Molecule Toroics and identify the coupling scheme that better reproduce the observed data.
