(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 + , y, z − 1; (vi) x + , −y + 1, z. Displacement ellipsoids are drawn at the 50% probability level. |
