Slow magnetic relaxation in a heteroleptic anilate-based DyIII metal–organic framework

Abstract

Novel heteroleptic anilate-based lanthanide MOFs (Ln^III = Tb, Dy, Ho) have been obtained under hydrothermal conditions by the ancillary ligand synthetic strategy. These structurally isomorphous species contain octacoordinated Ln^III ions with coordination polyhedra approaching an ideal D_2d symmetry, best described by a distorted biaugmented trigonal prismatic C_2v geometry. In the whole series, only the Dy-MOF exhibits SMM behaviour.
