1-[3-(2-Nitro-phen-yl)-5-phenyl-2-pyrazolin-1-yl]ethanone.

ABSTRACT: The title compound, C(17)H(15)N(3)O(3), was prepared from 1-(2-nitro-phen-yl)-3-phenyl-prop-2-en-1-one and hydrazine. The dihedral angle between the benzene and phenyl rings is 74.55?(2)°. The pyrazoline ring is in a slight envelope conformation with the C atom bonded to the phenyl ring forming the flap. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds connect mol-ecules into chains along [100].

(E)-1-(3-Methoxy-phen-yl)ethanone 4-nitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(15)H(15)N(3)O(3), were obtained from a condensation reaction of 4-nitro-phenyl-hydrazine and 3-methoxy-acetophenone. In the crystal structure, the methoxy-phenyl ring is twisted slightly with respect to the nitro-phenyl-hydrazine plane, making a dihedral angle of 14.81?(8)°. The nitro and meth-oxy groups are each coplanar with the attached benzene rings. The nitro-phenyl and methoxy-phenyl groups are located on opposite sides of the C=N double bond, indicating an E configuration of the mol-ecule. Adjacent mol-ecules are linked together via N-H?O hydrogen bonding, forming chains along the [101] direction.

(1E)-1-(3-Bromo-phen-yl)ethanone 2,4-di-nitro-phenyl-hydrazone.

Project description:The title compound, C(14)H(11)BrN(4)O(4), contains 3-bromo-phenyl and 2,4-dinitro-phenyl groups on opposite sides of a hydrazone unit and crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the two ring systems in each mol-ecule are 2.0 (1) and 2.5 (4)°. Weak C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.7269 (14) Å] help to establish the packing. Intra-molecular N-H⋯O hydrogen bonds are also observed. On one of the rings, the Br atom is disordered over two equivalent positions of the phenyl ring [occupancy ratio 0.8734 (10):0.1266 (10).

Project description:In the title compound, C19H18N2O3, the pyrazoline ring is close to being planar (r.m.s. deviation = 0.035?Å) and subtends dihedral angles of 2.11?(8) and 82.63?(8)° with the p-tolyl and benzene rings, respectively. In the crystal, C-H?O and C-H?N hydrogen bonds link the mol-ecules, forming a three-dimensional network. A weak C-H?? inter-action involving the benzene ring is also observed.

1-{2-[(E)-2-(2-Nitro-phen-yl)ethen-yl]-1-phenyl-sulfonyl-1H-indol-3-yl}ethanone.

Project description:In the title compound, C24H18N2O5S, the S atom has a distorted tetra-hedral configuration, with bond angles varying from 105.11?(7) to 119.98?(8)°. As a result of the electron-withdrawing character of the phenyl-sulfonyl group, the N-Csp (2) bond lengths [1.414?(2) and 1.413?(2)?Å] are slightly longer than the reported value of 1.355?(14)?Å for N atoms with a planar configuration. The indole moiety is essentially planar, with a maximum deviation of 0.0177?(14)?Å for the N atom. The phenyl ring of the sulfonyl substituent makes a dihedral angle of 85.70?(7)° with the mean plane of the indole moiety. The mol-ecular structure features intra-molecular C-H?O hydrogen bonds, which generate S(6) and S(12) ring motifs. In the crystal, adjacent mol-ecules are linked via C-H?O hydrogen bonds, forming infinite C(7) chains running along the a-axis direction. The crystal packing also features C-H?? inter-actions, which form a three-dimensional structure.

2-Bromo-1-(3-nitro-phen-yl)ethanone.

Project description:In the title compound, C(8)H(6)BrNO(3), there are two mol-ecules, A and B, in the asymmetric unit. The nitro and ethanone groups lie close to the plane of the benzene ring and the bromine atom is twisted slightly: the dihedral angles between the mean planes of the nitro and ethanone groups and the benzene ring are 4.6?(4) (A) and 2.8?(3) (B), and 0.8?(8) (A) and 5.5?(8)° (B), respectively. An extensive array of weak C-H?O hydrogen bonds, ?-? ring stacking [centroid-centroid distances = 3.710?(5) and 3.677?(5)?Å] and short non-hydrogen Br?O and O?Br inter-molecular inter-actions [3.16?(6)and 3.06?(8)?Å] contribute to the crystal stability, forming a supermolecular three-dimensional network structure along 110. These inter-actions give rise to a variety of cyclic graph-set motifs and form inter-connected sheets in the three-dimensional structure.

In the crystal, mol-ecules are linked by pairs of weak C-H?O hydrogen bonds into inversion dimers with R(2) (2)(16) graph-set motifs. The dimers are stacked along the b axis through further C-H?O hydrogen bonds.

2-[(2Z)-Azepan-2-yl-idene]-1-(4-nitro-phen-yl)ethanone.

Project description:The title compound, C(14)H(16)N(2)O(3), is an NH-vinyl-ogous amide (enaminone) produced by the reaction of 4-nitro-phenacyl bromide with azepane-2-thione. The conformation about the C=C bond [1.3927 (14) Å] is Z, which allows for the formation of an intra-molecular N-H⋯O hydrogen bond that leads to an S(6) loop. Inversion-related mol-ecules associate via N-H⋯O hydrogen bonds to form a 12-membered {⋯OC(3)NH}(2) synthon.
