5-Chloro-2-hy­droxy­benzaldehyde 4-ethyl­thio­semicarbazone

5-Bromo-2-hy­droxy­benzaldehyde 4-ethyl­thio­semicarbazone

In the title Schiff base compound, C10H12BrN3OS, the C-N-N-C torsion angle is 172.07 (11)°. An intra-molecular hydrogen bond exists between the hy-droxy H atom and the azomethine N atom. In the crystal, pairs of hydrogen bonds involving the imino H atom and the S atom give rise to supra-molecular dimers.

5-Chloro-2-hy­droxy­benzaldehyde thio­semicarbazone

In the title compound, C(8)H(8)ClN(3)OS, the whole mol-ecule assumes a planar structure, with an r.m.s. deviation of 0.108 (2) Å, and an intra-molecular O-H⋯N hydrogen bond generates and S(6) and ring motif. In the crystal structure, each of two pairs of inter-molecular N-H⋯S hydrogen bonds connects two mol-ecules, forming inversion dimers with R(2) (2)(8) motifs.

4-(Dimethyl­amino)benzaldehyde 4-ethyl­thio­semicarbazone

The title thio-semicarbazone derivative, C(12)H(18)N(4)S, features intra-molecular N-H⋯N and C-H⋯S hydrogen bonds which generate S(5) ring motifs. The dihedral angle between the benzene ring and the thio-urea unit is 6.30 (6)° indicating planarity in the mol-ecule. Inter-molecular N-H⋯S hydrogen bonds generate dimers with an R(2) (2)(8) ring motif. The methyl group of the N-ethyl residue is dis...

3-Eth­oxy-2-hy­droxy­benzaldehyde 2,4-di­nitro­phenylhydrazone N,N-di­methyl­formamide monosolvate

The Schiff base of the title compound, C(15)H(14)N(4)O(6)·C(3)H(7)NO, was obtained from the condensation reaction of 3-eth-oxy-2-hy-droxy-benzaldehyde and 2,4-dinitro-phenyl-hydrazine. The dihedral angle between the benzene rings is 3.05 (10)° and intra-molecular N-H⋯O and O-H⋯O hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal, the Schiff base and dimethyl-formami...
