N′-[(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(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...

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 carbohydrazide, C10H7N3O4S, the dihedral angle between the terminal five-membered rings is 27.4 (2)°, with these lying to the same side of the plane through the central CN2C(=O) atoms (r.m.s. deviation = 0.0403 Å), leading to a curved mol-ecule. The conformation about the C=N imine bond [1.281 (5) Å] is E, and the carbonyl O and amide H atoms are anti. In the crystal, N-H⋯O hydroge...
