Ethyl 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...
متن کاملMethyl 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 کاملGuanidinium 3-nitrobenzoate
The title compound, CH(6)N(3) (+)·C(7)H(4)NO(4) (-), an anhydrous guanidinium salt, shows a N-H⋯O hydrogen-bond network in which the guanidinium cation is involved in three cyclic R(2) (1)(6) hydrogen-bonding associations with separate carboxyl-ate O-atom acceptors. Further peripheral associations include a cyclic R(1) (2)(4) cation-anion inter-action, forming inter-linked undulating sheets in ...

In the title hydrated salt, CH(6)N(3) (+)·C(4)H(5)O(6) (-)·H(2)O, the deprotonated carboxyl group is disordered over two positions with a site-occupancy ratio of 0.945 (3):0.055 (3). The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this species. In the crystal structure, anions and water mol-ecules are...
