4-Amino-pyridinium picrate.

ABSTRACT: 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 bonds.

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 bonds. ...[more]

3-Amino-pyridinium picrate.

Project description: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 ?-? stacking inter-actions between symmetry-related pyridine and picric benzene rings with a centroid-centroid distance of 3.758?(2)?Å, forming a three-dimensional network.

2-Amino-pyridinium picrate.

Project description:In the title compound, C(5)H(7)N(2) (+)·C(6)H(2)N(3)O(7) (-), there are two crystallographically independent cations and anions (A and B) in the asymmetric unit. In both picrate anions, one of the nitro groups lies in the plane of the benzene ring [r.m.s. deviations = 0.014?(2) and 0.014?(2)?Å for anions A and B, respectively] and the other two are twisted away by 39.0?(2) and 18.8?(2)° in A, and 18.2?(1) and 2.5?(2)° in B. In the crystal, the cations and anions are linked by inter-molecular N-H?O and C-H?O hydrogen bonds, forming a two-dimensional network.

4-tert-Butyl-pyridinium picrate.

Project description: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 hydrogen bonds.

2-Amino-pyrimidinium picrate.

Project description:The geometric parameters of the title compound, C(4)H(6)N(3) (+)·C(6)H(2)N(3)O(7) (-), are in the usual ranges. While two nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 3.0?(2) and 4.4?(3)°], the third is significantly twisted out of this plane [dihedral angle 46.47?(8)°]. Anions and cations are connected via N-H?O hydrogen bonds. The mol-ecules crystallize in planes parallel to (11).

Crystal structure of 3-methyl-pyridinium picrate: a triclinic polymorph.

Project description:The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 3-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes in the triclinic space group P-1. The crystal structure of the monoclinic polymorph (space group P21/n) has been reported [Stilinovic & Kaitner (2011 ?). Cryst. Growth Des. 11, 4110-4119]. In the crystal, the anion and cation are linked via bifurcated N-H?(O,O) hydrogen bonds, enclosing an R 1 (2)(6) graph-set motif. These units are linked via C-H?O hydrogen bonds, forming a three-dimensional framework. Within the framework there are ?-? inter-actions present, involving inversion-related picrate anions and inversion-related pyridinium cations, with inter-centroid distances of 3.7389?(14) and 3.560?(2)?Å, respectively.

2-Amino-pyridinium trifluoro-acetate.

Project description:The asymmetric unit of the title compound, C(5)H(7)N(2) (+)·C(2)F(3)O(2) (-), contains four independent 2-amino-pyridinium cations and four independent trifluoro-acetate anions.

The ion pairs are linked into two independent chains along [100] by N-H?O hydrogen bonds. In addition, C-H?O and C-H?F hydrogen bonds and ??? inter-actions [centoid-centroid separation = 3.6007?(17)?Å] are observed.

1-Amino-pyridinium triiodidoplumbate(II).

Project description:The title complex, (C(5)H(7)N(2))[PbI(3)], consists of a 1-amino-pyridinium cation, disordered about a mirror plane, and a [PbI(3)](-) anion. The Pb(2+) ion (site symmetry ) is surrounded by six I atoms in a slightly distorted octa-hedral coordination. The PbI(6) octa-hedra share faces, building up (?) (1)[PbI(6/2)] chains running along [010]. The cations are situated between the chains. Coulombic attractions and van der Waals inter-actions between the inorganic and organic components are mainly responsible for the cohesion of the structure.
