1-[1-(4-Nitro-phen-yl)ethyl-idene]thio-semicarbazide.

ABSTRACT: The title compound, C(9)H(10)N(4)O(2)S, was prepared by the reaction of 1-(4-nitro-phen-yl)ethanone and thio-semicarbazide in ethanol at 367?K. There are weak inter-molecular N-H?S and N-H?O hydrogen-bonding inter-actions in the crystal structure involving the amine and nitrile groups, respectively, as donors.

Project description:In the title compound, C(15)H(10)FN(5)O(3)S, an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring, whereas N-H⋯O and C-H⋯S inter-actions complete S(6) ring motifs.

In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds to form C(8) chains along the [100] direction and C-H⋯O inter-actions are also observed.

1-(5-Nitro-2-oxoindolin-3-yl-idene)thio-semicarbazide.

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.

Project description:The title compound, C(17)H(16)N(4)OS, is stabilized in the form of a two-dimensional polymeric network due to inter-molecular N-H?S and N-H?O hydrogen bonds. An intra-molecular N-H?N hydrogen bond forms an S(5) ring, whereas inter-actions of the N-H?O and C-H?S types complete S(6) ring motifs. ?-? inter-actions with a centroid-centroid distance of 3.6514?(10)?Å are found between the ethyl-substituted benzene ring and the heterocyclic ring of the isatin derivative.

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].
