Figure 2
A view of the molecular structure of compound (II), with atom labelling. Displacement ellipsoids are drawn at the 50% probability level. Unlabelled atoms are related to the labelled atoms by the symmetry operation (−x, −y + 1, −z + 2) and the intramolecular C—H⋯O hydrogen bonds are shown as blue dashed lines (see Table 2). The minor component of the disordered pyridine ring, involving atom N3, is shown with black dashed lines. |
