(Z)-2-(2-Oxoindolin-3-yl-idene)-N-phenylhydrazinecarbothio-amide.

ABSTRACT: In the title compound, C(15)H(12)N(4)OS, the dihedral angle between the nine-membered indolin-2-one ring system and the phenyl ring is 2.72 (7)°. Intra-molecular cyclic N-H⋯O and C-H⋯S hydrogen-bonding inter-actions [graph set S(6)] are present, as are weak N-H⋯N inter-actions [graph set S(5)]. In the crystal, mol-ecules form centrosymmetric cyclic dimers through pairs of N-H⋯O hydrogen bonds [graph set R(2) (2)(8)] and these are extended by C-H⋯S inter-actions. The crystal structure also features weak C-H⋯π inter-actions.

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 ?-? stacking inter-actions [centroid-centroid distance = 3.849?(2)?Å].

(Z)-2-(5-Fluoro-2-oxoindolin-3-yl-idene)-N-phenyl-hydrazinecarbothio-amide.

Project description:The title compound, C(15)H(11)FN(4)OS, crystallizes with three independent mol-ecules (A, B and C) in the asymmetric unit. The dihedral angles between the nine-membered 5-fluoro-indolin-2-one ring system and the benzene ring are 22.14 (11), 12.56 (11) and 3.70 (11)° in mol-ecules A, B and C, respectively. In all three mol-ecules, intra-molecular cyclic N-H⋯O and C-H⋯S hydrogen-bonding inter-actions [graph set S(6)] are present in the N-N-C-N chain between the ring systems. In the crystal, the A mol-ecules form centrosymmetric cyclic dimers through inter-molecular N-H⋯O hydrogen bonds, which are linked into a supramolecular chain along [100] via C-H⋯F interactions; each type of hydrogen bond has graph set graph set R(2) (2)(8). A similar chain stabilised by similar interactions and also along [100] but, comprising alternating molecules of B and C is found. The latter chains are connected via C-H⋯S interactions, forming a layer with a zigzag topology parallel to (001).

Crystal structure of (Z)-2-(5-fluoro-2-oxoindolin-3-yl-idene)hydrazinecarbo-thio-amide.

Project description:In the title compound, C9H7FN4OS, the mol-ecules are almost planar, with an r.m.s. deviation of 0.047?(3)?Å from the mean plane defined by the non-H atoms and a maximum deviation of 0.123?(2)?Å for the amine N atom. The torsion angle for the N-N-C-S unit is 176.57?(19)°. In the crystal, mol-ecules are linked into inversion dimers via pairs of N-H?F hydrogen bonds and, additionally, through N-H?O and N-H?S hydrogen bonds, building a two-dimensional hydrogen-bond network parallel to the (103) plane. An intra-molecular N-H?O inter-action is also observed.

2-(5-Iodo-2-oxoindolin-3-yl-idene)hydrazinecarbo-thio-amide including an unknown solvate.

Project description:The mol-ecule of the title compound, C9H7IN4OS, is almost planar (r.m.s. deviation = 0.0373 Å). In the mol-ecule, N-H⋯N and N-H⋯O hydrogen bonds generate, respectively, S(5) and S(6) ring motifs. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating along [010]. These chains are linked via S⋯I contacts [3.4915 (16) Å], forming sheets lying parallel to (100). A region of disordered electron density, probably a disordered tetra-hydro-furan solvent mol-ecule, was treated using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. The formula mass and unit-cell characteristics were not taken into account during refinement.
