چکیده
In the asymmetric unit of the title benzofuran derivative, C(10)H(10)N(2)O(2), there are three crystallograpically independent mol-ecules, which are slightly twisted; the dihedral angle between the benzofuran ring system and the plane of the carbohydrazide unit is 8.64 (11)° in one mol-ecule, whereas the dihedral angles are 9.58 (11) and 6.89 (10)° in the other two mol-ecules. In the crystal, the three independent mol-ecules are linked to each other through N-H⋯N hydrogen bonds, forming a trimer. The trimers are further linked by weak N-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network. π-π inter-actions with centroid-centroid distances in the range 3.4928 (11)-3.8561 (10) Å are also observed.
