(E)-Methyl 1,3-thia-zol-2-yl ketone 2,4-dinitro-phenyl-hydrazone.

ABSTRACT: Crystals of the title compound, C(11)H(9)N(5)O(4)S, were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and methyl 1,3-thia-zol-2-yl ketone. Excluding two methyl H atoms, the mol-ecule displays a planar structure, the dihedral angle between the terminal thia-zole and benzene rings being 1.82?(8)°. The imino group links with adjacent nitro and thia-zole groups by intra-molecular bifurcated hydrogen bonding. The centroid-centroid separation of 3.7273?(11)?Å between nearly parallel benzene and thia-zole rings of adjacent mol-ecules indicates the existence of ?-? stacking in the crystal structure. Weak inter-molecular C-H?O hydrogen bonding is also observed.

(E)-2-Furyl methyl ketone 2,4-dinitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(12)H(10)N(4)O(5), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 2-furyl methyl ketone. The mol-ecule displays a nearly planar structure, and the furan ring is slightly twisted by a dihedral angle of 12.62?(6)° with respect to the phenyl-hydrazone plane. The face-to-face separation of 3.287?(7)?Å between parallel benzene rings of adjacent mol-ecules indicates the existence of ?-? stacking between dinitro-phenyl rings in the crystal structure.

Project description:The asymmetric unit of the title compound, C(13)H(8)Cl(2)N(4)O(4), contains two independent but similar and almost planar mol-ecules. An intra-molecular N-H?O hydrogen bond is observed in each mol-ecule.

1,3-Diphenyl-propan-2-one (2,4-dinitro-phen-yl)hydrazone.

Project description:In the title compound, C(21)H(18)N(4)O(4), there is an intra-molecular N-H?O hydrogen bond between the amino H atom and an O atom of the 2-nitro group of the adjacent benzene ring. The central benzene ring forms dihedral angles of 79.98?(7) and 82.88?(7)° with the two phenyl rings. In the crystal structure, mol-ecules are linked into a three-dimensional network by weak C-H?N, C-H?O and C-H?? inter-actions.

Phenyl N-(1,3-thia-zol-2-yl)carbamate.

Project description:In the title compound, C(10)H(8)N(2)O(2)S, the planes of the aromatic rings are oriented at a dihedral angle of 66.69?(3)°. In the crystal structure, inter-molecular N-H?N and C-H?O inter-actions link the mol-ecules into a two-dimensional network, forming R(2) (2)(8) ring motifs. ?-? contacts between the thia-zole rings [centroid-centroid distance = 3.535?(1)?Å] may further stabilize the structure. A weak C-H?? inter-action is also found.

2-Methoxy-benzaldehyde 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(14)H(12)N(4)O(5), an intra-molecular N-H?O hydrogen bond generates an S(6) ring motif. The dihedral angle between the two benzene rings is 3.91?(3)°, which shows the mol-ecule is almost planar. The para-nitro group is twisted from the benzene ring to which it is attached, making a dihedral angle of 8.50?(9)°. In the crystal structure, mol-ecules are linked together by inter-molecular C-H?O and inter-molecular three-centred O?O [2.8646?(12)-2.9213?(11)?Å] and O?N [3.0518?(11)?Å] inter-actions. The crystal structure is further stabilized by inter-molecular ?-? inter-actions [centroid-to-centroid distances 3.5708?(6)-3.9728?(12)?Å].

But-2-enal 2,4-dinitro-phenyl-hydrazone.

Project description:In the title compound, C(10)H(10)N(4)O(4), the but-2-enal chain is almost planar, the largest deviation from the mean plane being 0.013?(1)?Å, and this plane makes a dihedral angle of 9.95?(24)° with the benzene ring,. Of the two nitro groups, one is twisted with respect to the benzene ring, making a dihedral angle of 5.7?(1)°, whereas the other is nearly in the plane of the benzene ring, with a twist angle of only 0.7?(1)°. This difference is related to the occurence of an intra-molecular N-H?O hydrogen bond with the O atom of the less twisted nitro group. The NH group is also involved in a weak inter-action with the same O atom of a symmetry-related mol-ecule, thus forming a pseudo inversion dimer.

3-Penta-none 2,4-dinitro-phenyl-hydrazone.

Project description:Crystals of the title compound, C(11)H(14)N(4)O(4), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 3-penta-none. In the crystal structure, the mol-ecule, except one methyl group, displays a nearly planar structure. The imino group links to the adjacent nitro group via intra-molecular hydrogen bonding. The partially overlapped arrangement and face-to-face separation of 3.410?(9)?Å between parallel benzene rings indicate the existence of ?-? stacking between adjacent mol-ecules. The crystal structure also contains weak inter-molecular C-H?O hydrogen bonding.

4-Methyl-N-(4-methyl-phenyl-sulfon-yl)-N-[4-(4-methyl-phen-yl)-1,3-thia-zol-2-yl]benzene-sulfonamide.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C24H22N2O4S3. In each, the sulfonamide N atoms reveal nearly a trigonal-planar geometry with two S atoms of the O=S=O groups and one C atom of the thia-zole ring; the angles around the N atoms are between 117.00?(13) and 123.86?(9)°. The methyl-phenyl-sulfonyl groups are in anti conformations, forming dihedral angles of 78.00?(7)/72.53?(5) and 77.09?(6)/71.50?(7)° with the trigonal S-N-S planes in the two mol-ecules. The thia-zole groups are rotated around the C-N bonds and are almost perpendicular to the S-N-S plane [dihedral angles of 78.00?(7)/72.53?(5) and 77.09?(6)/71.50?(7)°]. In the crystal, pairs of C-H?O inter-actions, with the O atoms of the sulfonamide groups as acceptors, link each of the independent mol-ecules into inversion dimers.

N-(5-Chloro-1,3-thia-zol-2-yl)-2,4-difluoro-benzamide.

Project description:The title compound, C(10)H(5)ClF(2)N(2)OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2?(2)° and the equalization of the amide C-N bond lengths reveals the existence of conjugation between the benzene ring and the thia-zole unit. In the crystal, pairs of N-H?N hydrogen bonds link mol-ecules into inversion dimers. Non-classical C-H?F and C-H?O hydrogen bonds stabilize the crystal structure.
