3-Chloro-6-[2-(cyclo-pentyl-idene)hydrazin-1-yl]pyridazine.

ABSTRACT: The asymmetric unit of the title compound, C(9)H(11)ClN(4), contains two virtually planar mol-ecules that differ in conformation about the bond connecting the hydrazine and pyridazine units. The 3-chloro-6-hydrazinylpyridazine and cyclo-pentane groups are oriented at dihedral angles of 4.5?(3) and 8.8?(4)° in the two mol-ecules. In the crystal, the mol-ecules form a one dimensional polymeric structure extending along the a axis via N-H?N hydrogen bonds. The crystal stucired was an inversion twin [ratio of the twin domains = 0.73?(9):0.27?(9)].

3-Chloro-6-[2-(propan-2-yl-idene)hydrazin-yl]pyridazine.

Project description:In the title compound, C(7)H(9)ClN(4), the 3-chloro-6-hydrazinylpyridazine unit is planar (r.m.s. deviation = 0.0219?Å) and is oriented at a dihedral angle 4.66?(27)° with respect to the propan-2-yl-idene group. In the crystal, the mol-ecules are linked into non-planar dimers due to a crystallographic twofold rotation via N-H?N hydrogen bonds with R(2) (2)(8) graph-set ring motifs.

4-{2-[(E)-Cyclo-pentyl-idene]hydrazin-1-yl}benzene-sulfonamide.

Project description:The title mol-ecule, C(11)H(15)N(3)O(2)S, features a five-membered ring which is twisted about the middle CH(2)-CH(2) bond. The benzene ring is inclined with respect to the imine residue [C-N-N-C torsion angle = 165.4?(2)°]. Supra-molecular layers in the bc plane are formed by hydrogen bonds between the amine H atoms and sulfonamide O and imine N atoms, as well as by a weak hydrazine H-atom inter-molecular inter-action with the second sulfonamide O atom.

3-[(2E)-2-(Butan-2-yl-idene)hydrazin-yl]-6-chloro-pyridazine.

Project description:The asymmetric unit of the title compound, C(8)H(11)ClN(4), contains two independent mol-ecules (A and B) with slightly different conformations: the dihedral angles between the 3-chloro-6-hydrazinylpyridazine units and butyl side chains are 4.5?(2) and 11.98?(16)°. In the crystal, the A and B mol-ecules are linked by a pair of N-H?N hydogen bonds, generating an R(2) (2)(8) loop.

3-Chloro-6-[(E)-2-(1-phenyl-ethyl-idene)hydrazin-yl]pyridazine.

Project description:Two independent mol-ecules are present in the asymmetric unit of the title compound, C(12)H(11)ClN(4), (Z' = 2): the dihedral angles between the phenyl and pyridizine rings are 8.35?(10) and 37.64?(6)°. In the crystal, the two mol-ecules form inversion dimers with R(2) (2)(8) ring motifs through inter-molecular N-H?N hydrogen bonds. The crystal structure is stabilized by ?-? inter-actions between the pyridazine rings of symmetry-related molecules. In one of the independent mol-ecules, the centroid-centroid separations are 3.6927?(13) and 3.7961?(13)?Å, whereas in the other, the separations are 3.6909?(13) and 3.9059?(13)?Å.

Project description:In the title compound, C20H18BrN3S, the cyclo-pentane ring adopts a half-chair conformation. The 4-bromo-phenyl and phenyl rings make dihedral angles of 34.6?(1) and 68.52?(6)°, respectively, with the di-hydro-thia-zole ring. In the crystal, the mol-ecules pack in sheets approximately parallel to (101) which are formed by weak C-H?Br inter-actions.

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:The asymmetric unit of the title compound, C(30)H(48)ClN(3)O, contains two mol-ecules, A and B. In both mol-ecules, the three cyclo-hexane rings in the steroid fused ring systems adopt chair conformations, while the cyclo-pentane rings adopt envelope and twist conformations in mol-ecules A and B, respectively. In mol-ecule B, the cyano group is disordered over two orientations with refined site-occupancies of 0.593?(8) and 0.407?(8). An intra-molecular C-H?N inter-action forms an S(10) ring in both mol-ecules. In the crystal, mol-ecules are linked by N-H?O, C-H?O and C-H?N inter-actions, resulting is chains propagating along the a-axis direction.
