Figure 4
(a) Representation of the six-membered ring formed by N—H⋯O and C–H⋯O hydrogen bonds (blue dashed lines) between adjacent mol­ecules in the b-axis direction. (b) Representation of the seven-membered ring formed by N—H⋯O hydrogen bonds (blue dashed lines) between carbonyl and hydrazide groups of adjacent mol­ecules in the a-axis direction. Symmetry codes: (i) x, −y + 1, z; (iii) −x + [{3\over 2}], y, z − 1; (vi) x + [{1\over 2}], −y + 1, z. Displacement ellipsoids are drawn at the 50% probability level.
