Crystal structure of (E)-2-[(4-chloro-2H-chromen-3-yl)methyl-idene]-N-cyclo-hexyl-hydrazinecarbo-thio-amide.

ABSTRACT: In the title compound, C17H20ClN3OS, the mean plane of the central thio-urea core makes dihedral angles of 26.56?(9) and 47.62?(12)° with the mean planes of the chromene moiety and the cyclo-hexyl ring, respectively. The cyclo-hexyl ring adopts a chair conformation. The N-H atoms of the thio-urea unit adopt an anti conformation. The chromene group is positioned trans, whereas the cyclo-hexyl ring lies in the cis position to the thione S atom, with respect to the thio-urea C-N bond. In the crystal, mol-ecules are linked by N-H?S hydrogen bonds, forming inversion dimers enclosing R (2) 2(8) ring motifs. The dimers are linked by C-H?Cl hydrogen bonds, enclosing R (6) 6(44) ring motifs, forming sheets lying parallel to (010).

Crystal structures of two hydrazinecarbo-thio-amide derivatives: (E)-N-ethyl-2-[(4-oxo-4H-chromen-3-yl)methyl-idene]hydrazinecarbo-thio-amide hemi-hydrate and (E)-2-[(4-chloro-2H-chromen-3-yl)methyl-idene]-N-phenyl-hydrazinecarbo-thio-amide.

Project description:The title compounds, C13H13N3O2S·0.5H2O, (I), and C17H14ClN3OS, (II), are hydrazinecarbo-thio-amide derivatives. Compound (I) crystallizes with two independent mol-ecules (A and B) and a water mol-ecule of crystallization in the asymmetric unit. The chromene moiety is essentially planar in mol-ecules A and B, with maximum deviations of 0.028 (3) and 0.016 (3) Å, respectively, for the carbonyl C atoms. In (II), the pyran ring of the chromene moiety adopts a screw-boat conformation and the phenyl ring is inclined by 61.18 (9)° to its mean plane. In the crystal of (I), bifurcated N-H⋯O and C-H⋯O hydrogen bonds link the two independent mol-ecules forming A-B dimers with two R 2 (1)(6) ring motifs, and R 2 (2)(10) and R 2 (2)(14) ring motifs. In addition to these, the water mol-ecule forms tetra-furcated hydrogen bonds which alternately generate R 4 (4)(12) and R 6 (6)(22) graph-set ring motifs. There are also π-π [inter-centroid distances = 3.5648 (14) and 3.6825 (15) Å] inter-actions present, leading to the formation of columns along the c-axis direction. In the crystal of (II), mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. The dimers are linked by C-H⋯π inter-actions, forming ribbons lying parallel to (210).

2-(5-Chloro-2-oxoindolin-3-yl-idene)hydrazinecarbo-thio-amide.

Project description:The title mol-ecule, C9H7ClN4OS, is almost planar, with an r.m.s. deviation of 0.034 (2) Å for the mean plane through all the non-H atoms. Intra-molecular N-H⋯O and N-H⋯N hydrogen bonds form S(6) and S(5) ring motifs, respectively. In the crystal, mol-ecules are assembled into inversion dimers through pairs of co-operative N-H⋯Cl inter-actions. These dimers are connected along the b axis by N-H⋯O and N-H⋯S hydrogen bonds, generating layers parallel to (103). The layers are further connected along the a axis into a three-dimensional network, through weak π-π stacking inter-actions [centroid-centroid distance = 3.849 (2) Å].

Crystal structure of 2-[(E)-4-benz-yloxy-2-hy-droxy-benzyl-idene]-N-cyclo-hexyl-hydrazinecarbo-thio-amide aceto-nitrile hemisolvate.

Project description:The asymmetric unit of the title compound, C21H25N3O2S·0.5C2H3N, contains two independent mol-ecules with almost similar structural properties along with a solvent mol-ecule of aceto-nitrile. The compound exists in the E conformation with respect to the azomethine C=N double bond. The hydrazinecarbo-thio-amide moieties in both independent mol-ecules are almost planar [maximum deviations of 0.013 (2) and 0.007 (2) Å]. The mol-ecular conformation is stabilized in each case by an intra-molecular N-H⋯N hydrogen bond. In the crystal, pairs of N-H⋯S hydrogen bonds link each of the independent mol-ecules into inversion dimers. The dimers are inter-connected by means of three C-H⋯π inter-actions.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C12H15N3S, both of which display disorder of several C atoms in the N-bound ring (occupancy ratios of 0.75:0.25 in the first independent mol-ecule and 0.50:0.50 in the second) with the methyl H atoms also being disordered in the first mol-ecule (occupancy ratio of 0.70:0.30). The planes of the benzene ring and the N-N-C-N fragment make dihedral angles of 12.92 (14)° in the first independent mol-ecule and 7.60 (13)° in the second. In the crystal, mol-ecules are linked by weak N-H⋯S hydrogen bonds into chains along the a-axis direction. The crystal packing ressembles a herringbone arrangement.
