N-Cyclohexyl-N′-(4-nitrobenzoyl)thiourea
In the title compound, C14H17N3O3S, the nitro group is twisted slightly by 2.6 (3)° from the benzene ring plane and the thioureido group makes a dihedral angle of 52.06 (4)° with the benzene ring. The cyclohexyl ring displays a chair conformation. An intramolecular N—H⋯O interaction is present. In the crystal, intermolecular N—H⋯S hydrogen bonds link the molecules into centrosymmetric dimers. π–π interactions between inversion-related benzene rings (centroid–centroid distance = 4.044 Å) and C—H⋯π interactions (H⋯centroid distance = 3.116 Å) between one methylene cyclohexyl H atom and the benzene ring are also present
«El ingenioso hidalgo don Quijote» (1605), satire ménippéenne : (Prosas nuevas -V-: cartas, relaciones, «Lazarillos», «Guzmanes» y «Quijotes»)
Convocar marbetes como «novela» o «parodia de libros de caballerías» es tan natural que pocas veces nos fijamos en la tradición narrativa en la cual se situaba El ingenioso hidalgo don Quijote de la Mancha. Este artículo propone recuperar la vena jocoseria y los textos fundamentales de Luciano que hicieron posible la ficción de Cervantes. Sin atar el libro de 1605 al género de la sátira menipea, sí lo define como libro menipeano. La adaptación alemaniana (Primera parte de Guzmán de Alfarache) de la fórmula lucianesca vieja (Historia verdadera, El sueño) y nueva (Segunda parte del Lazarillo, Crotalón) no podía satisfacer a Cervantes : desde esta perspectiva de historia literaria, el Quijote constituye una propuesta narrativa alternativa de prosa menipeana.Utiliser des termes comme « roman » ou « parodie de livres de chevalerie » est tellement naturel que l'on a presque oublié de se demander à quelle tradition narrative se rattache El ingenioso hidalgo don Quijote de la Mancha. Cet article s'emploie à récupérer la veine sério-comique et les textes fondamentaux de Lucien de Samosate qui rendirent possible la fiction de Cervantès. Si ce livre n'est pas une satire ménippée, il n'en demeure pas moins un livre ménippéen. L'adaptation alémanienne (Primera parte de Guzmán de Alfarache) de la formule lucianesque ancienne (Histoire véritable, Le songe) et nouvelle (Segunda parte del Lazarillo, Crotalón) ne pouvait complètement satisfaire Cervantès : dans ce cadre, qui relève de l'histoire littéraire, on verra ainsi que le Quichotte constitue une proposition narrative alternative de prose ménippéenne.Using categories such as "novel" or "parody of tale of chivalry" is such a common thing that we rarely consider the narrative tradition within which El ingenioso hidalgo don Quijote de la Mancha fell. This article comes back to the jocoseria inspiration and those among Lucien's fundamental texts which made it possible for Cervantes's fiction to emerge. Without locking his 1605 text in the Menippean satire genre, Cervantes defines it as a Menippean book. Cervantes could not be satisfied with the adaptation by Mateo Alemán (Primera parte de Guzmán de Alfarache) of the old Lucianesque formula (Historia verdadera, El sueño) nor of the short story (Segunda parte del Lazarillo, Crotalón). Envisaged from such a perspective of literary history, the Quijote becomes an alternative to the narrative proposition of Menippean prose
3,5-Dinitro-N-(1,3-thiazol-2-yl)benzamide monohydrate
In the title compound, C10H6N4O5S·H2O, the thiazole ring is twisted at a dihedral angle of 25.87 (7)° with respect to the benzene ring. The water molecule is linked with the benzamide molecules via N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds. In the crystal, π–π stacking is observed between nearly parallel [dihedral angle = 7.02 (7)°] thiazole and benzene rings of adjacent molecules, the centroid–centroid distances being 3.7107 (9) and 3.7158 (9) Å, respectively
The 1:1 adduct of caffeine and 2-(1,3-dioxoisoindolin-2-yl)acetic acid
In the crystal structure of the title adduct [systematic name: 2-(1,3-dioxoisoindolin-2-yl)acetic acid–1,3,7-trimethyl-1,2,3,6-tetrahydro-7H-purine-2,6-dione (1/1)], C8H10N4O2·C10H7NO4, the components are linked by an O—H⋯N hydrogen-bond and no proton transfer occurs
N-(4-Bromophenyl)-3,5-dinitrobenzamide
The title molecule, C13H8BrN3O5, is slightly twisted, with the dihedral angle between the two benzene rings being 5.9 (1)°. In the crystal, N—H⋯O hydrogen bonds link the molecules into one-dimensional chains running along [101]. Further stabilization of the crystal structure is provided by π–π interactions [shortest centroid–centroid distance = 3.6467 (17) Å]
catena-Poly[[diaquacalcium]bis[μ-2-(1,3-dioxoisoindolin-2-yl)acetato]-κ3 O,O′:O;κ3 O:O,O′]
In the title complex, [Ca(C10H6NO4)2(H2O)2]n, the CaII atom lies on a twofold rotation axis and adopts a dodecahedral geometry. The CaII atom is octacoordinated by two O atoms from two water molecules and six O atoms from four acetate ligands. Each acetate acts as a tridentate ligand bridging two CaII atoms, resulting in a chain running along the c axis. O—H⋯O and C—H⋯O hydrogen bonds connect the chains into a two-dimensional network parallel to [011]. π–π interactions between adjacent isoindoline-1,3-dione rings [centroid–centroid distance = 3.4096 (11) Å] further consolidate the structure. One of the carboxylate O atoms is disordered over two sites in a 0.879 (12):0.121 (12) ratio
2,4-Dichloro-N-(1,3-thiazol-2-yl)benzamide
In the molecular structure of the title compound, C10H6Cl2N2OS, the dihedral angle between the benzene plane and the plane defined by the amide functionality is 8.6 (1)°, while the thiazole ring plane is twisted with respect to the amide plane by 68.71 (5)°. In the crystal, pairs of intermolecular N—H⋯N hydrogen-bond interactions connect the molecules into inversion dimers. π–π interactions are also observed between neighbouring thiazole and phenyl rings [centroid–centroid distance = 3.5905 (13) Å] and a weak C—H⋯π interaction also occurs
1-(4-Chlorophenyl)-3-(2-thienylcarbonyl)thiourea
The title compound, C12H9ClN2OS2, exists in the thioamide form with an intramolecular N—H⋯O hydrogen bond across the thiourea and the carbonyl group. The dihedral angle between the rings is 10.36 (11)°. In the crystal structure, molecules are linked into chains by weak intermolecular C—H⋯Cl hydrogen-bonding interactions
