N′-[(1E)-(4-Fluorophenyl)methylidene]thiophene-2-carbohydrazide
In the title compound, C(12)H(9)FN(2)OS, the thienyl ring is disordered over two positions, with the S atom of the major component [occupancy = 87.08 (16)°] oriented towards the ortho-H atom of the benzene ring. The mol-ecule is nearly planar, the dihedral angle between the thio-phene and benzene rings being 13.0 (2)° in the major component. The azomethine C=N double bond in the mol-ecule is of...
متن کاملN′-[(1E)-1-(2-Fluorophenyl)ethylidene]pyridine-3-carbohydrazide
The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine double bond whereas the N and methyl C atoms are in a Z conformation with respect to the same bond. The ketonic O and azomethine N atoms are cis to each other. The non-planar mol-ecule [the dihedral angle between the benzene rings is 7.44 (11)°] exists in an amido form with a C=O bond length of 1.221 (2) Å. ...

In the title compound, C(12)H(8)F(2)N(2)OS, the thienyl ring is disordered over two positions, with the S atom of the major component [occupancy = 75.03 (18)%] oriented away from an ortho-F atom of the benzene ring. The mol-ecule is nearly planar, the dihedral angle between the thio-phene and benzene rings being 6.19 (18) (in the major component) or 3.5 (6)° (in the minor component). The azomet...

In the title compound, C(13)H(12)N(2)OS, the dihedral angle between the aromatic rings is 14.84 (17)°. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
متن کاملN′-(4-Cyanobenzylidene)thiophene-2-carbohydrazide
The title compound, C(13)H(9)N(3)OS, was prepared by the reaction of thio-phene-2-carbohydrazide and 4-formyl-benzonitrile. The dihedral angle between the benzene and thio-phene rings is 11.9 (1)°. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by pairs of N-H⋯O hydrogen bonds.
