Key indicatorsSingle-crystal X-ray study T = 298 K Mean (C-C) = 0.003 Å R factor = 0.048 wR factor = 0.118 Data-to-parameter ratio = 13.2 For details of how these key indicators were automatically derived from the article, see A view of (I) (Farrugia, 1997). Displacement ellipsoids are drawn at the 50% probability level. The intramolecular hydrogen bond between O1 and H1 (on N1) is indicated as a dashed line.
