3-Bromoanilinium picrate
In the title compound, C(6)H(7)BrN(+)·C(6)H(2)N(3)O(7) (-), the O atoms of two of the nitro groups are disordered over two sites, the ratios of the refined occupancies being 0.72 (6):0.28 (6) and 0.74 (5):0.26 (5). In the crystal structure, the anions and cations are linked via inter-molecular N-H⋯O hydrogen bonds into chains along [100]. Further stabilization is provided by weak inter-molecula...
متن کامل3-Aminopyridinium picrate
During the formation of the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), a phenolic proton is transferred to the pyridine N atom. In the crystal structure, the ions are linked by inter-molecular N-H⋯O and N-H⋯(O,O) hydrogen bonds into layers running parallel to (100). These layers are connected by weak π-π stacking inter-actions between symmetry-related pyridine and picric benzene rin...
متن کامل3-Benzyl-1-methylimidazolium picrate
In the title salt, C(11)H(13)N(2) (+)·C(6)H(2)N(3)O(7) (-), the dihedral angles between the benzene ring in the cation and the imidazolium ring and the benzene ring of the picrate anion are 113.7 (2) and 116.3 (2)°, respectively. The imidazolium ring is nearly parallel to the benzene ring of the picrate anion, the dihedral angle between the planes being 2.6 (1)°. The nitro groups in the picrate...
متن کامل3-Chloro-4-fluoroanilinium picrate
In the title picrate salt of a dihalogenated aniline derivative, C(6)H(6)ClF(+)·C(6)H(2)N(3)O(7) (-), the intra-cyclic C-C-C angles in the picrate anion cover a broad range [111.95 (12)-125.38 (13)°], while those in the aromatic cation span a much narrower range [118.25 (14)-122.33 (13)°]. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts, connect the ions into layers pa...
متن کامل3-(1H-Imidazol-1-yl)propanaminium picrate
IN THE TITLE SALT [SYSTEMATIC NAME: 3-(1H-imidazol-1-yl)propanaminium 2,4,6-tri-nitro-phenolate], C6H12N3 (+)·C6H2N3O7 (-), there are five independent cation-anion pairs (A, B, C, D, E) in the asymmetric unit. In the cation, the ammonium group is protonated with the amino-propyl group nearly at right angles to the mean plane of the imidazole ring showing C-N-C-C torsion angles ranging from 79.6...
