ABSTRACT: The title compound, C(12)H(12)Cl(2)N(2)O(3), crystallizes as a non-merohedral twin with a twinning ratio of 0.51:0.49. The mol-ecule adopts a keto-hydrazo tautomeric form stabilized by an intra-molecular N-H?O hydrogen bond. The configuration around the N-N bond is trans.

Ethyl 2-[(4-chloro-phen-yl)hydrazono]-3-oxobutanoate.

Project description:The mol-ecule of the title oxobutanoate derivative, C(12)H(13)ClN(2)O(3), is nearly planar; the inter-planar angle between the benzene ring and the mean plane through the hydrazono-3-oxobutanoate unit is 2.69 (3)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal packing, C-H⋯O(3-oxo) inter-actions link mol-ecules into dimers. The dimers thus formed are linked through C-H⋯O(carboxyl-ate C=O) inter-actions, leading to the formation of ribbons along the [01] direction, which are stabilized via Cl⋯Cl [3.2916 (3) Å] contacts. The ribbons are stacked via C⋯O contacts [3.2367 (12)-3.3948 (12) Å].

Ethyl 2-[(3-chloro-phen-yl)hydrazono]-3-oxobutanoate.

Project description:The mol-ecule of the title oxobutanoate derivative, C(12)H(13)ClN(2)O(3), adopts a keto-hydrazo tautomeric form and is roughly planar, the angle between the benzene ring and the mean plane through the hydrazone and aliphatic chain being 1.49 (6)°. This planarity is further aided by the formation of an intra-molecular N-H⋯O hydrogen bond which generates an S(6) ring motif. The aromatic ring and aliphatic chain have a trans configuration with respect to the N-N bond. In the crystal packing, centrosymmetric R(2) (2)(16) dimers are formed through pairs of weak C-H⋯O(3-oxo) inter-actions. These dimers are linked together through weak C-H⋯O(carboxyl-ate C=O) inter-actions into ribbons along the b-axis direction. These ribbons are stacked along the a-axis direction. The crystal also exhibits Cl⋯Cl [3.4988 (6) Å] and C⋯O [3.167 (2)-3.335 (2) Å] short contacts.

Ethyl 2-[(2,6-dimethyl-phen-yl)hydrazono]-3-oxobutanoate.

Project description:The title compound, C(14)H(18)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit, having closely comparable geometries. Both mol-ecules are essentially planar [maximum deviations from the mean plane of 0.069?(1) and 0.068?(1)?Å for the two mol-ecules] and contain an intra-molecular N-H?O hydrogen bond which generates a ring with graph-set motif S(6). In the crystal, the mol-ecules are linked into chains along the c axis by inter-molecular C-H?O hydrogen bonds, and inter-molecular C-H?? inter-actions are also present.

Ethyl 2-chloro-[2-(4-chloro-phen-yl)hydrazin-1-yl-idene]acetate.

Project description:The title compound, C(10)H(10)Cl(2)N(2)O(2), features a planar C(ar)-N(H)-N=C(Cl) unit [torsion angle = 5.5 (4)°] whose benzene substituent is coplanar with it [dihedral angle = 4.7 (4)°]; this unit is slightly twisted with respect to the carboxyl -CO(2) fragment [dihedral angle = 2.2 (52)°]. The amino group acts as a hydrogen-bond donor to the carbonyl O atom of an adjacent mol-ecule; the hydrogen bond generates a helical polymer that runs along the b axis of the monoclinic unit cell.

Project description:In the title compound, C(10)H(11)ClN(2)O, the dihedral angle between the acetohydrazide group and the aromatic ring is 33.76?(9)°. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds generate R(2) (2)(8) loops.

(E)-1-[1-(2-Chloro-phen-yl)ethyl-idene]-2-(2,4-dinitro-phen-yl)hydrazine.

Project description:The title mol-ecule, C(14)H(11)ClN(4)O(4), is in an E configuration and is twisted with the dihedral angle between the two benzene rings being 38.48 (8)°. The ethyl-idenehydrazine plane makes dihedral angles of 6.03 (10) and 44.04 (11)°, respectively, with the dinitro- and chloro-substituted benzene rings. The two nitro groups are essentially coplanar with the bound benzene ring, making dihedral angles of 0.9 (2) and 1.65 (18)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by a weak C-H⋯O inter-action into a chain along the c axis. The chains are further stacked along the b axis by a π-π inter-action with a centroid-centroid distance of 3.6088 (10) Å.

Ethyl 4-{1-[(2,4-dinitro-phen-yl)hydrazono]eth-yl}-5-(2-naphthyl-methoxy-meth-yl)isoxazole-3-carboxyl-ate.

Project description:The title compound, C(26)H(23)N(5)O(8), was prepared and its structure investigated to further develop a working hypothesis for the essential binding pharmacophore for ligands of the System Xc- transporter [Patel et al.

The secondary amino NH group forms an intra-molecular N-H?O hydrogen bond to a ring nitro group. There is a dihedral angle of 44.27?(5)° between the isoxazole plane and the hydrazone group plane.

Ethyl N-(2-benzoyl-4-chloro-phen-yl)-ethane-carboximidate.

Project description:In the title compound, C(17)H(16)ClNO(2), the N=C-O-C-C fragment is planar within 0.029?(1)?Å, and makes dihedral angles of 66.71?(8) and 59.61?(8)° with the planes of the chloro-phenyl and benzoyl rings, respectively. The carbonyl C=O bond is not coplanar with either of the aromatic rings; it makes angles of 42.5 and 23.5° with the normals to the ring planes. In the crystal, very weak C-H?O, C-H?Cl, C-H?? and ?-? [inter-planar distance = 3.53?(1)?Å] inter-actions are observed.
