Crystal structures of (E)-4-[1-(2-carbamothioylhydrazinylidene)ethyl]phenyl acetate and (E)-4-[1-(2-carbamothioylhydrazinylidene)ethyl]phenyl benzoate
In the title compounds, C11H13N3O2S, (I), and C16H15N3O2S, (II), the thio-semicarbazone group adopts an extended conformation. The acetate ester (I) crystallizes with two independent mol-ecules in the asymmetric unit. In the benzoate ester (II), the planes of the two aryl rings are inclined to one another by 46.70 (7)°. In both compounds, there is a short intra-molecular N-H⋯N contact present, ...
متن کاملCrystal structure of 4-{(E)-[2-(pyridin-4-ylcarbonyl)hydrazin-1-ylidene]methyl}phenyl acetate monohydrate
The asymmetric unit of the title compound, C15H13N3O3·H2O, comprises a 4-{(E)-[2-(pyridin-4-ylcarbon-yl)hydrazinyl-idene]meth-yl}phenyl acetate mol-ecule and a solvent water mol-ecule linked by O-H⋯O and O-H⋯N hydrogen bonds from the water mol-ecule and a C-H⋯O contact from the organic mol-ecule. The compound adopts an E conformation with respect to the azomethine bond and the dihedral angle be...
متن کاملCrystal structure of (E)-2-[(4-hydroxybenzylidene)azaniumyl]benzoate
The title Schiff base, C14H11NO3, crystallizes as a zwitterion (i.e. proton transfer from the carb-oxy-lic acid group to the imine N atom). The dihedral angle between the aromatic rings is 19.59 (6)° and an intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (4)(24) loops. The dimers are linked by C-H⋯O i...
متن کاملSynthesis, Crystal Structure and Antimicrobial Activity of (E)-ethyl-4-(2-oxoacenaphthylen-1(2H)-ylideneamino) benzoate
A Schiff base, (E)-ethyl-4-(2-oxoacenaphthylen-1(2H)-ylideneamino)benzoate, (E4AB) had been synthesized in good yield by the acid-catalyzed condensation reaction of acenaphthenequinone and ethyl-4-aminobenzoate in methanolic solution. The synthesized compound was elucidated by elemental analysis (CHN), FTIR, H-NMR, C-NMR and single crystal X-ray diffraction. E4AB crystallized in the monoclinic ...
متن کامل(E)-2-Methoxy-4-(3-oxobut-1-enyl)phenyl acetate
The title compound, C(13)H(14)O(4), belongs to the class of α,β-unsaturated ketones, which have potential bactericidal, fungicidal, anti-tumor and anti-inflammatory properties. The C atoms and attached H atoms of the ethenyl part of the title mol-ecule are disordered over two orientations with refined occupancies of 0.583 (7) and 0.417 (3). Mol-ecules are connected by two inter-molecular C-H⋯O ...
