title: 2-(9,10-Anthraquinon-2-yl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazole-3-oxide-1-oxyl: polymorphism in a conjugated anthraquinone-substituted nitronylnitroxide.
abstract: Two polymorphs of an anthraquinone-nitronylnitroxide radical, AntQNN, were isolated, both with antiferromagnetic (AFM) exchange attributed to chain-type inter-radical contacts: one with J1D/k ≈ -3 K, and one with J1D/k ≈ -17 K.
