2-Amino-pyridinium picrate.

ABSTRACT: 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.

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.

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)°.

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 π-π 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-3-methyl-pyridinium 2-amino-5-methyl-pyridinium sulfate monohydrate.

Project description:The asymmetric unit of the title compound, 2C(6)H(9)N(2) (+)·SO(4) (2-)·H(2)O, contains two isomeric protonated amino-methyl-pyridine cations, a sulfate anion and a solvent water mol-ecule. The cations are in the iminium tautomeric form. In the crystal structure, inter-molecular O-H?O, N-H?O and weak C-H?O hydrogen bonds link the components into a three-dimensional network. Additional stabilization is provided by weak ?-? stacking inter-actions, with centroid-centroid distances of 3.758?(2) and 3.774?(1)?Å.

Crystal structure of a second triclinic polymorph of 2-methyl-pyridinium picrate.

Project description:The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 2-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes with two cations and two anions in the asymmetric unit. In the crystal, the cations are linked to the anions via bifurcated N-H?(O,O) hydrogen bonds, generating R 1 (2)(6) graph-set motifs. Numerous C-H?O hydrogen bonds are observed between these cation-anion pairs, which result in a three-dimensional network. In addition, weak aromatic ?-? stacking between the 2-methyl-pyridinium rings [inter-centroid distance = 3.8334?(19)?Å] and very weak stacking [inter-centroid distance = 4.0281?(16)?Å] between inversion-related pairs of picrate anions is observed. The title salt is a second triclinic polymorph of the structure (also with Z' = 2) reported earlier [Anita et al. (2006). Acta Cryst. C62, o567-o570; Chan et al. (2014 ?). CrystEngComm, 16, 4508-4538]. In the title compound, the cations and anions display a chequerboard arrangement when viewed down [100], whereas in the first polymorph, (010) layers of alternating cations and anions are apparent in a [100] view. It is inter-esting that the unit-cell lengths are almost identical for the two polymorphs, although the inter-axial angles are quite different.

(R)-2-{2-[(S)-(2'-Benzo-yloxy-1,1'-binaphthyl-2-yl)oxycarbonyl-amino]-3-phenylpropanamido-meth-yl}pyridinium picrate acetone solvate.

Project description:In the crystal structure of the title compound, C(43)H(34)N(3)O(5) (+)·C(6)H(2)N(3)O(7) (-)·C(3)H(6)O, the large dimension and shape of the cation are responsible for the elongation of the ortho-rhom-bic unit cell. The ions and acetone mol-ecules are linked together by a system of hydrogen bonds involving an inter-molecular hydrogen bond between one N atom of the cation and the O atom of acetone and two inter-molecular hydrogen bonds between the cation N atoms and the O atoms of the picrate anion. No intra-molecular hydrogen bonds exist in the structure. The dihedral angle between the two naphthalene ring systems is 76.16?(13)°. The chiral C atom has a known R configuration, but this cannot be confirmed from this X-ray analysis.

The dihedral angle between the ring and the CO(2) group in the anion is 7.14?(7)°.
