4-(Dimethyl-amino)benzaldehyde 4-ethyl-thio-semicarbazone.

ABSTRACT: 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 disordered and was refined with site occupancies of 0.521?(5) and 0.479?(5).

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.

Project description:The mol-ecular conformation of the title compound, C(10)H(13)N(3)O(2)S, is stabilized by an intramolecular O-H?N hydrogen bond. Adjacent mol-ecules are linked by O-H?O hydrogen bonds to furnish a zigzag chain.

Benzaldehyde thio-semicarbazone.

Project description:The title compound, C(8)H(9)N(3)S, contains two mol-ecules in the asymmetric unit. One mol-ecule is close to being planar (r.m.s. deviation from the mean plane = 0.06?Å for the non-H atoms), while the other exhibits a dihedral angle of 21.7?(1)° between the benzene ring and the mean plane of the thio-semicarbazone unit. Inter-molecular N-H?S hydrogen bonds link the mol-ecules into layers parallel to the (010) plane.

4-(Diphenyl-amino)-benzaldehyde 4-phenyl-thio-semicarbazone.

Project description:The title mol-ecule, C(26)H(22)N(4)S, is composed of three main parts, viz. a triphenyl-amine group is connected to a phenyl ring by a thio-semicarbazone moiety. The C= N double bond has an E conformation. The crystal packing is dominated by strong hydrogen bonds through the thio-semicarbazone moiety, with pairs of N-H?S hydrogen bonds linking the mol-ecules to form inversion dimers with an R(2) (2)(8) ring motif. An intra-molecular N-H?N hydrogen bond is also present, generating an S(5) ring motif. Although the structure contains four phenyl rings, ?-? stacking inter-actions are not formed between them, probably due to the conformation adopted by the triphenyl-amine group. However, a weak ?-? stacking inter-action is observed between the phenyl ring and the delocalized thio-semicarbazone moiety.

(E)-3,4-Dihydroxy-benzaldehyde 4-ethyl-thio-semicarbazone.

Project description:The title compound, C(10)H(13)N(3)O(2)S, was prepared by condensation of 3,4-dihydroxy-benzaldehyde with 4-ethyl-3-thio-semicarbazide. The mol-ecule adopts an E configuration with respect to the C=N bond. One of the OH substituents on the dihydroxy-benzene ring is disordered over the two possible 3-positions on either side of the ordered 4-hydr-oxy group. The occupancy of the major disorder component refined to 0.633?(7). The mol-ecule is essentially planar, with an r.m.s. deviation through all non-H atoms of 0.0862?Å. An intra-molecular N-H?N hydrogen bond forms between the outer amine residue and the imine N atom, generating an S(5) ring motif and contributing to the planarity of the mol-ecule. In the crystal structure, an extensive network of classical O-H?O, O-H?S and N-H?S hydrogen bonds and weak C-H?O and S?O [3.301?(3)?Å] inter-actions link mol-ecules into sheets running approximately parallel to the ab plane.

(E)-2,4-Dihydroxy-benzaldehyde 4-ethyl-thio-semicarbazone-4,4'-bipyridine-water (4/7/2).

Project description:The asymmetric unit of the title compound, 7C(10)H(8)N(2)·4C(10)H(13)N(3)O(2)S·2H(2)O, contains two independent 2,4-hydroxy-benzaldehyde 4-ethyl-thio-semicarbazone mol-ecules, three and a half 4,4'-bipyridine mol-ecules and one water mol-ecule. Two of the 4,4'-bipyridine mol-ecules lie on general positions and the other three on centers of inversion. The two 4,4'-bipyridine mol-ecules on general positions and one of the three on special positions are disordered over two positions each with an occupancy of 0.50. The -NH-C(=S)-NH-NC fragment is close to planar in the two 2,4-hydroxy-benzaldehyde 4-ethyl-thio-semicarbazone mol-ecules (r.m.s. deviations = 0.04 and 0.05 Å). In the crystal, the Schiff base, N-heterocycle and water mol-ecules engage in O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bonding inter-actions, generating a layer structure.
