Figure 1
Displacement ellipsoid plot (Spek, 2020) of a molecule in 1; ellipsoids are drawn at 70% probability, H atoms are shown as spheres of arbitrary radii. Selected distances (Å) and angles (°): N1—N2 1.358 (4), N2—C1 1.351 (4), C1—C2 1.360 (5), C2—C3 1.392 (4), N2—C4 1.448 (4), C3—N1—N2 104.2 (3), C1—C2—C3 106.6 (3). |
