3-Methyl-1-benzofuran-2-carbohydrazide.

ABSTRACT: 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. ?-? inter-actions with centroid-centroid distances in the range 3.4928?(11)-3.8561?(10)?Å are also observed.

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 ...[more]

N'-[(E)-4-Bromo-benzyl-idene]-1-benzofuran-2-carbohydrazide monohydrate.

Project description:The title compound, C(16)H(11)BrN(2)O(2)·H(2)O, exists in a trans conformation with respect to the N=C bond [1.2815 (14) Å] and the benzofuran ring system forms a dihedral angle of 2.96 (5)° with the benzene ring. In the crystal, the ketone O atom accepts two O-H⋯O and one C-H⋯O hydrogen bond, and the water O atom accepts an N-H⋯O inter-action. Together, these lead to infinite layers lying parallel to (100).

An intra-molecular N-H?N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H?(O,N) and C-H?O hydrogen bonds into a tape along the c axis and these tapes are further connected by another weak C-H?O hydrogen bond into a sheet parallel to the bc plane. ?-? inter-actions [centroid-to-centroid distances = 3.4845?(12)-3.6250?(13)?Å] are also observed.
