An asymmetrically connected hexanuclear DyIII6 cluster exhibiting slow magnetic relaxation

Abstract

A new hexanuclear dysprosium(III) cluster [Dy6(L)7(HL)(MeOH)2(H2O)(OH)2(OAc)] (1) has been synthesized from the schiff base ligand o-phenolsalicylimine and dysprosium nitrate. This unique DyIII6 cluster, constituted of an exclusive combination of two vertex-sharing and one edge-sharing high-anisotropy Dy3 triangles assembled together forming an unprecedentedly asymmetric homometallic DyIII6 core, shows slow relaxation of the magnetization.
