1-(5-Bromo-2-oxoindolin-3-yl-idene)thio-semicarbazone.

ABSTRACT: The title mol-ecule, C9H7BrN4OS, is essentially planar [r.m.s. deviation = 0.066?(2)?Å], the maximum deviation from the mean plane through the non-H atoms being 0.190?(3)?Å for the terminal amine N atom. In the crystal, mol-ecules are linked through N-H?O and N-H?S inter-actions, generating infinite chains along the b-axis direction. In turn, the chains are stacked along the a axis via ?-? inter-actions [centroid-centroid distance = 3.470?(2)?Å] and further connected by N-H?Br inter-actions into a three-dimensional network. An intra-molecular N-H?O hydrogen bond is also observed.

The title mol-ecule, C9H7BrN4OS, is essentially planar [r.m.s. deviation = 0.066 (2) Å], the maximum deviation from the mean plane through the non-H atoms being 0.190 (3) Å for the terminal amine N atom. In the crystal, mol-ecules are linked through N-H⋯O and N-H⋯S inter-actions, generating infinite chains along the b-axis direction. In turn, the chains are stacked along the a axis via π-π inter-actions [centroid-centroid distance = 3.470 (2) Å] and further connected by N-H⋯Br inter-actions into ...[more]

1-(5-Bromo-2-oxoindolin-3-yl-idene)-4-phenyl-thio-semicarbazide.

Project description:In the title compound, C15H11BrN4OS, the least-squares plane through the 5-bromo-isatin fragment forms a dihedral angle of 13.63 (14)° with the phenyl ring.

Project description:In the title molecule, C(9)H(7)N(5)O(3)S, there is an intramolecular N-H⋯O. The molecule is essentially planar, with the maximum deviation from the mean plane of the 18 non-H atoms being 0.135 (2) Å for the amine N atom. In the crystal, the molecules are connected via intermolecular N-H⋯O and N-H⋯S hydrogen bonds, forming two-dimensional networks lying parallel to (10[Formula: see text]). They are separated by an interplanar distance of 3.3214 (9) Å, leading to π-π interactions which stabilize the crystal structure.

4-(3-Fluoro-phen-yl)-1-(propan-2-yl-idene)thio-semicarbazone.

Project description:The title compound, C(10)H(12)FN(3)S, crystallizes in the same space group (P2(1)/c) as two polymorphic forms of 4-phenyl-1-(propan-2-yl-idene)thio-semicarbazone [Jian et al. (2005). Acta Cryst. E61, o653-o654; Venkatraman et al. (2005). Acta Cryst. E61, o3914-o3916]. The arrangement of mol-ecules relative to the twofold screw axes is similar to that in the crystal structure of the lower density polymorph. In the solid state, the mol-ecular conformation is stabilized by an intra-molecular N-H⋯N hydrogen bond. The mol-ecules form centrosymmetric R(2) (2)(8) dimers in the crystal through pairs of N-H⋯S hydrogen bonds.

4-(3-Fluoro-phen-yl)-1-(2-oxoindolin-3-yl-idene)thio-semicarbazide.

Project description:In the title compound, C(15)H(11)FN(4)OS, there are three independent mol-ecules, each with a disordered 3-fluoro-phenyl group [occupancy ratios = 0.547 (17):0.453 (17), 0.645 (5):0.355 (5) and 0.626 (15):0.374 (15)] and displaying dihedral angles of 4.2 (3), 25.2 (6) and 32.4 (5)° between the 2-oxoindoline and fluoro-substituted phenyl rings. Strong intra-molecular N-H⋯N and N-H⋯O and weak intra-molecular C-H⋯S hydrogen bonds complete S(5) and S(6) ring motifs, while strong inter-molecular N-H⋯O hydrogen bonds inter-connect the three independent mol-ecules through R(3) (3)(12) ring motifs. The three-mol-ecule units are in turn linked into polymeric sheets via C-H⋯F and C-H⋯S hydrogen bonds and π-π inter-actions [centroid-centroid distances in the range 3.520 (2)-3.820 (9) Å].

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].

1-(2-Oxoindolin-3-yl-idene)-4-[2-(tri-fluoro-meth-yl)phen-yl]thio-semicarbazide.

Project description:In the title compound, C(16)H(11)F(3)N(4)OS, the dihedral angle between the aromatic ring systems is 69.15 (10)°. Intra-molecular N-H⋯N and N-H⋯O hydrogen bonds generate S(5) and S(6) rings, respectively. A short N-H⋯F contact also occurs. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. The dimers are linked by N-H⋯F hydrogen bonds, forming polymeric chains propagating in [100]. π-π inter-actions also exist between the centroids of the benzene rings of the 2-oxoindoline group at a distance of 3.543 (3) Å and a short C=O⋯π contact occurs. Two F atoms of the trifluoro-methyl group are disordered over two sets of sites in a 0.517 (8):0.483 (8) ratio.
