Figure 1
The molecular structure of the two independent molecules (1 and 2) of the title compound. Displacement ellipsoids are drawn at the 50% probability level. The N—H⋯O hydrogen bonds are shown as dashed lines (see Table 1), and unlabelled atoms are related to labelled atoms by symmetry operations −x + 1, −y + 1, −z + 1 for molecule 1 and −x + 2, −y, −z + 1 for molecule 2. |
