Methyl 3-carboxy-5-nitrobenzoate
The structure of the title compound, C(9)H(7)NO(6), is essentially planar [maximum deviation 0.284 (2)Å] except for the methyl H atoms. The crystal structure is stabilized by asymmetric O-H⋯O hydrogen bonds linking the hydrogen carboxyl-ates into pairs around the inversion centres. There is also π-π stacking of the benzene rings [centroid-centroid distance 3.6912 (12) Å].
متن کاملEthyl 4-anilino-3-nitrobenzoate
In the title compound, C(15)H(14)N(2)O(4), the aromatic rings are oriented at a dihedral angle of 78.33 (3)°. An intra-molecular N-H⋯O hydrogen bond results in a non-planar six-membered ring with a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π contacts between the phenyl rings and both the phenyl and benzene rings, [centroid...

In the title compound, C(10)H(9)NO(6), the carb-oxy, ethoxy-carbonyl and nitro groups form dihedral angles of 3.8 (1), 4.5 (1) and 164.8 (1)°, respectively, with the mean plane of the benzene ring. In the crystal structure, mol-ecules lying about inversion centers are linked through O-H⋯O hydrogen bonds. C-H⋯O inter-actions are also present.
متن کاملEthyl 4-acetyl-5-oxo-3-phenylhexanoate
The reaction of ethyl 3-bromo-3-phenyl-propano-ate with pentane-2,4-dione, in the presence of palladium(II) acetate and triphenyl-phosphine, in dimethyl-formamide, unexpectedly gave the title product, C(16)H(20)O(4). The mol-ecule contains one chiral C atom but the crystal is racemic. In the crystal, neighboring mol-ecules form a chain along [100] through three weak C-H⋯O inter-actions. Further...
متن کاملEthyl 5-(4-aminophenyl)isoxazole-3-carboxylate
The asymmetric unit of the title compound, C(12)H(12)N(2)O(3), contains two mol-ecules in which the benzene and isoxazole rings are almost coplanar, the dihedral angles between their mean planes being 1.76 (9) and 5.85 (8)°. The two mol-ecules inter-act with each other via N-H⋯N and N-H⋯O hydrogen bonds, which link the mol-ecules into layers parallel to the ac plane. The layers stack in a paral...
