4-tert-Butylpyridinium picrate
In the title compound, C(9)H(14)N(+)·C(6)H(2)N(3)O(7) (-), the three nitro groups of the picrate anion are twisted out of the plane of the attached benzene ring; the dihedral angles are 32.8 (2), 10.5 (4) and 12.3 (4)°. The pyridinium cations and picrate anions are linked via bifurcated N-H⋯(O,O) hydrogen bonds. The ionic pairs are linked into a ribbon-like structure along [101] by C-H⋯O hydrog...
متن کامل4-Acetylpiperazinium picrate
In the title salt, C6H13N2O(+)·C6H2N3O7 (-) (systematic name: 4-acetyl-piperazin-1-ium 2,4,6-tri-nitro-phenolate), the piperazin-1-ium ring has a slightly distorted chair conformation. In the picrate anion, the mean planes of the two o-NO2 and p-NO2 groups are twisted with respect to the benzene ring by 15.0 (2), 68.9 (4) and 4.4 (3)°, respectively. In the crystal, N-H⋯O hydrogen bonds are obse...
متن کامل4-Nitrophenylhydrazinium picrate monohydrate
In the crystal structure of the title compound, C6H8N3O2 (+)·C6H2N3O7 (-)·H2O, N-H⋯O and O-H⋯O hydrogen bonds link the components into a two-dimensional network parallel to (010). In addition, there are pairs of weak inversion-related C-H⋯O hydrogen bonds within the two-dimensional network. The three nitro groups are twisted by 1.6 (3), 7.8 (3) and 12.1 (3)° from the ring plane in the anion, wh...
متن کامل4-Aminopyridinium picrate
In the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), the 4-amino-pyridinium cation is essentially planar (r.m.s. deviation = 0.002 Å). The three nitro groups in the picrate anion are twisted away from the attached benzene ring [dihedral angles = 24.1 (1), 9.3 (3) and 21.4 (1)°]. In the crystal structure, the ions are linked into a three-dimensional network by N-H⋯O and C-H⋯O hydrogen b...
متن کامل4-(2-Chloroethyl)morpholinium picrate
The title compound, C(6)H(13)ClNO(+)·C(6)H(2)N(3)O(7) (-), was synthesized from picric acid and 4-(2-chloro-ethyl)morpholine. The crystal structure is stabilized by C-H⋯O and N-H⋯O hydrogen-bond inter-actions.
