3-[(2E)-2-(Butan-2-ylidene)hydrazinyl]-6-chloropyridazine
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.
متن کامل(2E,3E)-3-(Pyrazin-2-yloxyimino)butan-2-one oxime
In the title compound, C(8)H(10)N(4)O(2), all non-H atoms are nearly coplanar [maximum deviation 0.1256 (16) Å for the methyl C furthest from the ring]. Inter-molecular O-H⋯N hydrogen bonds link adjacent mol-ecules into a one-dimensional zigzag chain along the c axis. There is also a weak π-π stacking inter-action between neighbouring pyrazine rings, with a centroid-centroid distance of 4.0432 ...
متن کاملMethyl (2E)-2-({2-[(2E)-2-benzylidene-3-methoxy-3-oxopropyl]-1,3-dioxoindan-2-yl}methyl)-3-phenylprop-2-enoate
In the title compound, C(31)H(26)O(6), the five-membered ring of the indane unit adopts a slight envelope conformation with the flap atom displaced by 1.38 (14) Å. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond, which generates an S(9) ring motif. In the crystal, pairs of C-H⋯O hydrogen bonds link centrosymmetrically related mol-ecules into dimers, generatin...
متن کامل(2E)-2-(3-Ethoxy-2-hydroxybenzylidene)hydrazinecarboxamide
The title compound, C10H13N3O3, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. A classical intra-molecular O-H⋯N hydrogen bond is present. The two N atoms of the hydrazinecarboxamide unit are also involved in inter-molecular N-H⋯O hydrogen bonds, with the O atom of the hydrazinecarboxamide group acting as the acceptor. Pairs of N-H⋯O hydrogen bo...

In a search for new leads towards potent antimicrobial agents, an array of novel (2E)-ethyl-2-(2-(2,4-dinitrophenyl)hydrazono)-4-(naphthalen-2-yl)-6-arylcyclohex-3-ene carboxylates 17-24 were synthesized and characterized through their melting point, elemental analysis, MS, FT-IR, one-dimensional NMR (1H, D2O exchanged 1H and 13C), two dimensional HOMOCOR and HSQC spectroscopic data. In-vitro m...
