2-(1H-Indol-3-yl)-4,4,5,5-tetramethylimidazolidine-1-oxyl 3-oxide

Abstract

In the title compound, C15H18N3O 2, the plane of the indole ring system is twisted with respect to the plane of the nitronyl nitroxide moiety, exhibiting a dihedral angle of 21.61 (6)°. The crystal packing is stabilized by N - H⋯O hydrogen bonds and weak C - H⋯O interactions.
