Coexistence of intermolecular ferromagnetic interaction and [NHN]+ hydrogen bond in N-protonated m-pyridyl nitronyl nitroxide
Abstract
Reaction of 2-(3-pyridyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1-oxyl 3-N-oxide (m-PYNN) and HBr gas gives rise to the complex (m-PYNN)2HBr, in which the coexistence of an intermolecular ferromagnetic interaction and an [NHN]+ hydrogen bond is found.
