| Abstract |
Controlling the coordination sphere of lanthanoid complexes is a challenging critical step toward controlling their relaxation properties. Here we present the synthesis of hexacoordinated dysprosium single-molecule magnets, where tripodal ligands achieve a near-perfect octahedral coordination. We perform a complete experimental and theoretical investigation of their magnetic properties, including a full single-crystal magnetic anisotropy analysis. The combination of electrostatic and crystal-field computational tools (SIMPRE and CONDON codes) allows us to explain the static behavior of these systems in detail. |
See more Dysprosium products. Dysprosium (atomic symbol: Dy, atomic number: 66) is a Block F, Group 3, Period 6 element with an atomic radius of 162.5. 
The number of electrons in each of dysprosium's shells is [2, 8, 18, 28, 8, 2] and its electron configuration is [Xe]4f10 6s2. The dysprosium atom has an atomic radius of 178 pm and a Van der Waals radius of 229 pm. Dysprosium was first discovered by Paul Emile Lecoq de Boisbaudran in 1886. In its elemental form, dysprosium has a silvery-white appearance. 
It is a member of the lanthanide or rare earth series of elements and, along with holmium, has the highest magnetic strength of all other elements on the periodic table, especially at low temperatures. Dysprosium is found in various minerals including bastnäsite, blomstrandine, euxenite, fergusonite, gadolinite, monazite, polycrase and xenotime. It is not found in nature as a free element. The element name originates from the Greek word dysprositos, meaning hard to get at.
