A 3D MOF constructed from dysprosium(iii) oxalate and capping ligands: ferromagnetic coupling and field-induced two-step magnetic relaxation

Abstract

A novel 3D MOF based on dysprosium(III) oxalate and 1,10-phenanthroline (phen), {[Dy(C₂O₄)_1.5phen]·0.5H₂O}_n (1), has been hydrothermally synthesized. The Dy³⁺ ion acts as a typical Y-shaped node, linking to each other to generate an interesting 3D topology structure. Complex 1 is the first 3D DyMOF displaying both ferromagnetic coupling and field-induced two-step magnetic relaxation.
