Chemistry and Physics of Supramolecular Magnetic Materials

TLDR

The authors build multidimensional magnetic materials from the precursor [Cu(opba)]2- and characterize their magnetic properties using polarized neutron diffraction and magnetic measurements. The reaction with other paramagnetic species produces one‑, two‑, and interlocked networks whose spin density maps precisely describe the ground state and exhibit antiferro‑, ferri‑, and ferromagnetic long‑range order.

Abstract

The building of multidimensional magnetic materials obtained with the molecular precursor [Cu(opba)]2- is described. The reaction with other paramagnetic species (3d or 4f metal ions, organic radicals) yielded one-dimensional, two-dimensional, and interlocked networks. The magnetic properties of these systems are reviewed using polarized neutron diffraction and magnetic measurements. It is shown that the spin density maps give a precise description of the ground state of such molecular magnetic species. Moreover, different long-range magnetic orderings (antiferro-, ferri-, and ferromagnetic) have been obtained.
