Figure 1
The molecular structure of the title compound showing the atom-labeling scheme and displacement ellipsoids drawn at the 50% probability level. Intramolecular N—H⋯O hydrogen bonds are shown as red dotted lines and N—H⋯N hydrogen bonds as blue dotted lines. Non-labeled atoms are generated by inversion symmetry [symmetry code: (i) 1 − x, −y, 1 − z]. |
