In the title mol-ecule, C(11)H(14)N(2)O(3), the acetohydrazide group is planar 0.084 (1) Å and forms a dihedral angle of 19.7 (1)° with the benzene ring. One of the meth-oxy groups is coplanar with the attached benzene ring within 0.052 (3) Å, whereas the other is slightly twisted [C-O-C-C = 6.3 (3)°]. The mol-ecule adopts a trans configuration with respect to the C=N bond. In the crystal, the mol-ecules are linked into chains along the a axis by N-H⋯O hydrogen bonds and the chains are cross-linked into a three-dimensional network by C-H⋯O hydrogen bonds.
在标题分子C(11)H(14)N(2)O(3)中,乙酰肼基团呈平面状,偏差为0.084 (1) Å,与苯环形成19.7 (1)°的二面角。其中一个甲氧基与相连的苯环共面,偏差在0.052 (3) Å以内,而另一个则略有扭曲[C-O-C-C = 6.3 (3)°]。分子相对于C=N键呈反式构型。在晶体中,分子通过N-H⋯O氢键沿a轴连接成链,这些链通过C-H⋯O氢键交联成三维网络。
