The crystal structure of a new phase of the pnitrophenyl nitronyl &oxide radical compound is described. A study of its magnetic properties reveals the largest intermolecular ferromagnetic coupling reported so far among a series of polymorphs of this compound.
X-ray crystal analysis and magnetic measurements reveal the ferromagnetic linear chain with JF/kB=0.27 K in an a-nitronyl nitroxide, 2-(4-pyridyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1 -oxyl 3-N-oxide.
Transition to a ferromagnetic long-range ordered state was found at 0.60 Kin the orthorhombic Pphase crystal ofg-nitrophenyl nitronyl nitroxide (or 2-(4'-nitrophenyl)-4,4,5,5-tetramethyl-4,5dihydro-lH-imidazol-l-oxyl-3-N-oxide in the IUPAC nomenclature). This finding follows our recent discovery of
