(Z)-Ethyl 2-chloro-2-[2-(4-methylphenyl)hydrazinylidene]acetate
The mol-ecule of the title compound, C11H13ClN2O2, is approximately planar (r.m.s. deviation = 0.099 Å for non-H atoms) and adopts a Z conformation about the C=N double bond. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds to the same O-atom acceptor, forming zigzag chains propagating along [010]. These inter-actions give rise to R2(1)(6) loops.

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 ...
متن کاملEthyl (Z)-2-chloro-2-(2-phenylhydrazin-1-ylidene)acetate
The title compound, C(10)H(11)ClN(2)O(2), features an almost planar C(ar)-N(H)-N=C(Cl) unit [torsion angle = 0.8 (1)° whose phenyl substituent is almost coplanar with it [dihedral angle = 2.8 (2)°]; this unit is slightly twisted with respect to the carboxyl -CO(2) fragment [dihedral angle = 10.3 (2)°]. In the crystal, the amino group acts as a hydrogen-bond donor to the carbonyl O atom of an ad...
متن کامل(Z)-Ethyl 2-oxo-3-(1,2-dihydroquinolin-2-ylidene)propanoate
Both independent mol-ecules in the asymmetric unit of the tautomeric title compound, C(14)H(13)NO(3), a synthetic product obtained from 2-lithio-methyl-quinoline and diethyl oxalate, crystallize in the enaminone form with a Z configuration around the double bond. Intra-molecular N-H⋯O hydrogen bonds occur, generating an S(6) graph-set motif. In the crystal, weak inter-molecular C-H⋯O and π-π st...
متن کامل(Z)-Ethyl 2-hydroxyimino-2-(4-nitrobenzyl)ethanoate
The title mol-ecule, C(11)H(10)N(2)O(6), has a Z conformation about the C=N bond of the oxime unit. There are significant twists from planarity throughout the mol-ecule, the most significant being between the hydroxy-imino and ester groups which are effectively orthogonal with an N-C-C-O(carbon-yl) torsion angle of 91.4 (2)°. The crystal packing features oxime-benzoyl O-H⋯O contacts that lead t...
