Ethyl (3E)-3-[2-(4-bromo-phenyl-sulfon-yl)hydrazin-1-yl-idene]butano-ate.

ABSTRACT: The asymmetric unit of title compound, C(12)H(15)BrN(2)O(4)S, contains two mol-ecules (A and B), with slightly different conformations: the bromo-phenyl rings and the SO(2) planes of the sulfonyl groups are oriented at dihedral angles of 50.2?(2) (mol-ecule A) and 58.24?(7)° (mol-ecule B), and the ethyl acetate groups make dihedral angles of 63.99?(19)° (A) and 65.35?(16)° (B) with their bromo-phenyl groups. In the crystal, both mol-ecules exist as inversion dimers linked by pairs of N-H?O hydrogen bonds, which generate R(2) (2)(14) loops. The dimers are linked by C-H?O inter-actions.

The asymmetric unit of title compound, C(12)H(15)BrN(2)O(4)S, contains two mol-ecules (A and B), with slightly different conformations: the bromo-phenyl rings and the SO(2) planes of the sulfonyl groups are oriented at dihedral angles of 50.2 (2) (mol-ecule A) and 58.24 (7)° (mol-ecule B), and the ethyl acetate groups make dihedral angles of 63.99 (19)° (A) and 65.35 (16)° (B) with their bromo-phenyl groups. In the crystal, both mol-ecules exist as inversion dimers linked by pairs of N-H⋯O hydro ...[more]

Ethyl 4-(phenyl-sulfon-yl)piperazine-1-carboxyl-ate.

Project description:In the title compound, C(13)H(18)N(2)O(4)S, the piperazine ring adopts a chair conformation. The dihedral angle between the least-squares planes through the piperazine and benzene rings is 73.23?(10)°. In the crystal, there are no classical hydrogen bonds but stabilization is provided by weak C-H?? inter-actions.

Ethyl 3-[2-(p-tolyl-carbamothio-yl)hydrazinyl-idene]butano-ate.

Project description:The title compound, C(14)H(19)N(3)O(2)S, was obtained from a condensation reaction of N-(p-tol-yl)hydrazinecarbothio-amide and ethyl acetoacetate. The mol-ecule assumes an E configuration; the thio-semicarbazide and ester groups are located on the opposite sides of the C=N bond. The almost planar thio-semicarbazide unit (r.m.s. deviation = 0.0130?Å) is tilted at a dihedral angle of 49.54?(12)° with respect to the benzene ring. Inter-molecular N-H?N and N-H?S hydrogen bonding stabilizes the crystal structure. The eth-oxy group of the ester unit is disordered over two positions, with a site-occupancy ratio of 0.680?(10):0.320?(10).

N'-[(1E,2E)-1-(2-Phenyl-hydrazin-1-yl-idene)-1-(phenyl-sulfon-yl)propan-2-yl-idene]benzohydrazide.

Project description:The configuration about each C=N bond in the title compound, C(22)H(20)N(4)O(3)S, is E. While to a first approximation the phenyl-hydrazin-1-yl-idene and benzohydrazide residues are coplanar, in part due to the presence of an intra-molecular N-H?N hydrogen bond, significant twists are evident in the orientations of the hydrazine [N-N-C-C torsion angle = -170.74?(11)°] and benzoyl benzene [N-C-C-C = -21.72?(18)°] rings. The sulfonyl benzene ring occupies a position almost normal to the rest of the mol-ecule [C-S-C-N = -92.28?(10)°]. Centrosymmetric aggregates mediated by pairs of hydrazide-sulfonyl N-H?O hydrogen bonds are the predominant packing motif in the crystal. These are connected into linear supra-molecular chains via C-H?O inter-actions which are, in turn, linked into layers in the ac plane via C-H?? inter-actions. Connections between layers along the b-axis direction are of the ?-? type and occur between centrosymmetrically related hydrazine-bound benzene rings [centroid-centroid separation = 3.7425?(9)?Å].

Ethyl 3-oxo-2-(2-phenyl-hydrazinyl-idene)butano-ate: a re-determination.

Project description:The previous crystallographic studies [Wang et al. (2005 ?). Huaxue Yanjiu16, 29-32; Wang et al. (2007 ?). Youji Huaxue, 27, 524] of the title compound, C(12)H(14)N(2)O(3), gave only the unit-cell dimensions and an R factor with no other details available: the full structure is presented here. The eth-oxy group is disordered over two orientations with refined occupancies of 0.642?(15):0.358?(15). The nine C atoms and two N atoms of the 1-phenyl-2-(propan-2-yl-idene)hydrazine segment of the mol-ecule are close to being coplanar, with a maximum deviation of 0.0779?(14)?Å for the phenyl-amino N atom and an intra-molecular N-H?O hydrogen bond generates an S(6) ring. In the crystal, pairs of C-H?O hydrogen bonds link mol-ecules into inverson dimers, generating R(2) (2)(16) loops.

Ethyl 2-[(Z)-2-benzyl-hydrazin-1-yl-idene]-2-bromo-acetate.

Project description:In the title compound, C(11)H(13)BrN(2)O(2), the dihedral angle between the phenyl ring and the almost planar (r.m.s. deviation = 0.011 Å) C-C(Br)=N-N(H)- fragment is 74.94 (16)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, which generate C(6) chains propagating in [010]. Weak aromatic π-π stacking [centroid-centroid separation = 3.784 (3) Å] may also help to consolidate the packing.
