(E)-2-Hydroxynaphthalene-1-carbaldehyde semicarbazone
The title compound, C(12)H(11)N(3)O(2), adopts an E or trans configuration with respect to the C=N bond. There is an intra-molecular O-H⋯N hydrogen bond involving the hydroxyl H atom and an N atom of the hydrazine group. In the crystal structure, mol-ecules are connected via N-H⋯O hydrogen bonds, forming a three-dimensional network.

In the title compound, C(9)H(11)N(3)O, the benzene ring is disordered over two positions with refined occupancies of 0.922 (5) and 0.078 (5). The program PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155] recommends the solution in the space group C2/m with a = 7.3050 (3), b = 6.6745 (2), c = 18.3853 (6) Å and β = 96.986 (2)°. However, the large number of non-extinct reflections needed to be igno...
متن کامل2-Methoxynaphthalene-1-carbaldehyde
In the title compound, C(12)H(10)O(2), the aldehyde and meth-oxy groups are slightly twisted around the single bonds that join them to the naphthalene ring system. In the crystal structure, mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds, forming chains running along the c axis.
متن کامل(E)-1-(4-Fluorophenyl)ethan-1-one semicarbazone
In the title compound, C(9)H(10)FN(3)O, the semicarbazone group is nearly planar, with the maximum deviation of 0.044 (1) Å for one of the N atoms. The mean plane of semicarbazone group forms a dihedral angle of 30.94 (4)° with the benzene ring. The mol-ecules are linked into a supra-molecular chain by N-H⋯O hydrogen bonds formed along the c axis. The crystal structure is further stabilized by ...
متن کامل(E)-1-(4-Bromophenyl)ethan-1-one semicarbazone
In the title compound, C(9)H(10)BrN(3)O, the hydrazone portion and aliphatic chain are essentially coplanar [maximum deviation 0.057 (15) Å] and the mean plane makes a dihedral angle of 70.9 (6)° with the benzene ring. The main feature of the crystal structure is the inter-molecular N-H⋯O hydrogen bond, which links mol-ecules into zigzag chains along the a axis. These chains are further stacked...
