Slow Magnetic Relaxation in a Hydrogen-Bonded 2D Array of Mononuclear Dysprosium(III) Oxamates

The reaction of N-(2,6-dimethylphenyl)­oxamic acid with dysprosium­(III) ions in a controlled basic media afforded the first example of a mononuclear lanthanide oxamate complex exhibiting a field-induced slow magnetic relaxation behavior typical of single-ion magnets (SIMs). The hydrogen-bond-mediated self-assembly of this new bifunctional dysprosium­(III) SIM in the solid state provides a unique example of 2D hydrogen-bonded polymer with a herringbone net topology.
