Figure 1
The molecular structure of the two independent molecules (A and B) of the title compound, showing the atom labelling. Displacement ellipsoids are drawn at the 50% probability level. The torsion angles C2—N1—C3—O2 and C3—N1—C2—O1 are −1.8 (3) and −91.5 (2)°, respectively, for molecule A, and C5—N2—C6—O4 and C6—N2—C5—O3 are −2.1 (3) and −95.7 (2)°, respectively, for molecule B. |
