3-Ethynyl-2,2,5,5-tetramethyl-1-oxyl-3-pyrroline

The five-membered ring of the title compound, C10H14NO, is almost planar [mean deviation from best plane = 0.006 (1) Å]. The N-O bond is in the plane of the five-membered ring. The molecule is positioned about a pseudo-mirror plane at y = 0.375. In the crystal, molecules are connected by intermolecular C-H...O contacts into layers parallel to (010). Key indicators: single-crystal X-ray study; T = 167 K; mean σ(C–C) = 0.002 Å; R factor = 0.062; wR factor = 0.157; data-to-parameter ratio = 27.3.
