Incorporation of a nitrogen-rich energetic ligand in a {Yb III2} complex exhibiting slow relaxation of the magnetisation under an applied field

Abstract

Though often used as the precursor in energetic materials research and organic synthesis, 3,6-dihydrazinyl-1,2,4,5-tetrazine (dhtz) has not been previously explored in coordination chemistry. Herein, we present the first crystalline coordination compound with dhtz, [Yb₂(dhtz)(fod)₆] (fod⁻ = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate). This compound exhibits Single-Molecule Magnet behaviour under an applied magnetic field, and m_J states were resolved through luminescence studies.
