Synthesis, crystal structure, and magnetic properties of 5‐methyl‐l,2,4‐triazole‐nitronyl nitroxide: A one‐dimensional compound with unusually large ferromagnetic intermolecular interactions

Abstract

Triazole nitronyl nitroxide radicals and their derivatives are open‐shell molecules with potential applications as building blocks for the synthesis of multi‐property molecular materials. The title compound (see figure) exhibits exceptionally strong ferromagnetic interactions. Its synthesis, crystallographic data and magnetic properties are described. Possible mechanisms for the origin of these properties are suggested. magnified image
