Structural and magnetic characterization of α- and β-2,4-hexadiyne-1,6-diyl bis(2,2,5,5-tetramethyl-1-oxyl-3-pyrroline-3-carboxylate) and its thermal degradation product
Abstract
Two polymorphs of the titled diradical have been characterized by X-ray diffraction, vibrational spectroscopies, and magnetic susceptibility; its radiation or thermal induced polymerization has not been achieved.
