N'-[(4Z)-1-(3-Methyl-5-oxo-1-phenyl-4,5-di-hydro-1H-pyrazol-4-yl-idene)hex-yl]benzene-sulfono-hydrazide.

ABSTRACT: In the title compound, C22H26N4O3S, the dihedral angle between the pyrazoloneand phenyl rings is 21.73?(4)°. The benzensulfono-hydrazide group adopts a gauche conformation about the N-N vector. The C-N-N-S torsion angle is -109.88?(13)°. The mol-ecule exists as the enamine tautomeric form (C=C-NH). An intra-molecular N-H?O=C hydrogen bond occurs. In the crystal, mol-ecules are linked by pairs of N-H?O=C hydrogen bonds, forming centrosymmetric dimers.

Crystal structure of (Z)-N'-[1-(3-methyl-5-oxo-1-phenyl-1,5-di-hydro-4H-pyrazol-4-yl-idene)prop-yl]benzene-sulfono-hydrazide.

Project description:The title compound, C19H20N4O3S, was synthesized by refluxing equimolar amounts of 1-phenyl-3-methyl-4-propionylpyrazol-5-one and benzene-sulfonyl hydrazide in ethanol. The compound crystallizes in the keto form and the carbonyl O atom forms an intra-molecular N-H?O hydrogen bond with the neighbouring NH group. There is also C-H?O short contact involving the neighbouring phenyl ring. Probably as a result of this, the phenyl ring is inclined to the pyrazolone ring by only 7.58?(12)°. The dihedral angle between the phenyl ring and the benzene-sulfonyl ring is 22.78?(11)°. In the crystal, mol-ecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers with an R (2) 2(14) ring motif. The dimers are linked via pairs of C-H?O hydrogen bonds, forming chains propagating along [100].

Project description:With respect to the aliphatic planar five-membered ring (r.m.s. deviation = 0.011?Å) of the title compound, C(15)H(13)N(3)O(2)S, the phenyl ring is aligned at 6.9?(1)° and the phenyl-ene ring at 2.4?(1)°, so that the three rings are nearly coplanar. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the ketonic O atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.

Project description:The title compound, C17H24N2O3S, was synthesized in order to determine the relative configuration of the corresponding ?-keto aldehyde. In the U-shaped mol-ecule, the five-membered ring approximates an envelope with the methyl-ene atom adjacent to the quaternary C atom being the flap. The dihedral angles between the four nearly coplanar atoms of the five-membered ring and the flap and the aromatic ring are 38.8?(4) and 22.9?(2)°, respectively. The bond angles around the S atom are in the range 104.11?(16)-119.95?(16)°. In the crystal, mol-ecules are linked via N-H?O by hydrogen bonds, forming a chain along the a-axis direction.

Crystal structure of N'-[(E)-(4-chloro-phen-yl)(phen-yl)methyl-idene]-4-methyl-benzene-sulfono-hydrazide.

Project description:The title compound, C20H17ClN2O2S, was obtained by a condensation reaction between 4-chloro-benzo-phenone and tosyl hydrazide. The plane of the methyl-substituted benzene ring forms dihedral angles of 20.12 (12) and 78.43 (13)° with those of the chlorine-substituted benzene ring and the benzene ring, respectively, with the last two rings forming a dihedral angle of 67.81 (13)°. The chlorine substituent was also found to be 0.868 (2):0.132 (2) disordered over these two rings. In the crystal, mol-ecules are linked through pairs of N-H⋯O hydrogen bonds, giving centrosymmetric cyclic dimers [graph set R 2 (2)(8)], which are linked by weak C-H⋯O and C-H⋯Cl inter-actions into a chain structure which extends along the a-axis direction.

Project description:In the title compound, C21H16ClN3O2, the pyrazolone ring and the O=C-C=C-N mean plane [maximum deviation = 0.022 (2) Å] are nearly coplanar, making a dihedral angle 4.56 (8)°, while the phenyl and pyrazole rings subtend a dihedral angle of 19.75 (8)°. The compound is in the enamine-keto form and its structure is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, mol-ecules are linked via C-H⋯N hydrogen bonds, forming chains along [010]. Between the chains there are π-π inter-actions [inter-centroid distances = 3.3902 (9) and 3.5956 (11) Å], linking the chains to form sheets parallel to (10-1).

Project description:In the title compound, C(20)H(19)FN(4)O(4)S, the pyrazole and benzene-sulfonamide rings are coplanar [dihedral angle = 5.02?(15)°] but this planarity does not extend over the entire mol-ecule, the dihedral angle between the terminal six-membered rings being 33.24?(14)°. Intra-molecular hy-droxy-hy-droxy O-H?O and amine-hy-droxy N-H?O hydrogen bonds, as a well as a tight C-H?O(carbon-yl) inter-action, lead to a sequence of three fused S(6) rings. Supra-molecular chains along the a axis feature in the crystal packing; these chains are stabilized by amine-sulfonamide N-H?O and amine-pyrazole N-H?N hydrogen bonds.
