Figure 2
Representation of the dihedral angle α formed by the planes containing carbon chain atoms C1, C2, C3, C4, and C5 (blue plane) and the hydrazine group atoms N1, N2, O1, C1, and C2 (grey plane) in 1. Grey: carbon; red: oxygen; blue: nitrogen. H atoms atoms were omitted for clarity. Displacement ellipsoids are drawn at the 50% probability level. |
