Crystal structure of (E)-N'-{[(1R,3R)-3-isopropyl-1-methyl-2-oxo-cyclo-pent-yl]methyl-idene}-4-methyl-benzene-sulfono-hydrazide.

ABSTRACT: 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.

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].
