Figure 1
ORTEP-3 plots (Farrugia, 1997) of (a) (I) and (b) (II), in comparable orientations, with the atom-numbering schemes. Displacement ellipsoids are shown at the 30% probability level. H atoms are shown as small spheres of arbitrary radii and the dashed lines represent intramolecular C—H⋯O and C—H⋯π interactions. |
