2-Amino-5-methyl-pyridinium 2-hydr-oxy-3,5-dinitro-benzoate.

ABSTRACT: In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.023?(1)?Å. There is an intra-molecular O-H?O hydrogen bond in the 3,5-dinitro-salicylate anion, which generates an S(6) ring motif. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. Weak inter-molecular C-H?O inter-actions help to further stabilize the crystal structure.

Bis(quinolin-8-ol)silver(I) 2-hydr-oxy-3,5-dinitro-benzoate.

Project description:The title compound, [Ag(C(9)H(7)NO)(2)](C(7)H(3)N(2)O(7)), was prepared from 3,5-dinitro-salicylic acid (DNS), quinolin-8-ol and AgNO(3). The Ag(I) atom is coordinated by two N atoms and two O atoms from two quinolin-8-ols in a roughly planar [maximum deviation = 0.223?(2)?Å] environment. The two quinolin-8-ol ligands are bent slightly with respect to each other, making a dihedral angle of 9.55?(9)°. The DNS anion inter-acts with the silver complex through O-H?O hydrogen bonds.

Methyl 2-methyl-3,5-dinitro-benzoate.

Project description:In the title compound, C(9)H(8)N(2)O(6), the methyl ester group is almost planar (r.m.s. deviation = 0.002 Å) and is oriented at a dihedral angle of 24.27 (16)° with respect to the benzene ring. The nitro groups make dihedral angles of 4.2 (5)° and 60.21 (11)° with the benzene ring. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, resulting in zigzag chains.

4-Methyl-anilinium 3,5-dinitro-benzoate.

Project description:The crystal structure of the title compound, C(7)H(10)N(+)·C(7)H(3)N(2)O(6) (-), displays N-H⋯O hydrogen bonding between the ammonium groups and the O atoms of the 3,5-dinitro-benzoate anions. Inter-molecular C-H⋯O inter-actions further stabilize the packing. An O atom of each of the nitro groups is disordered over two sites with site occupancy factors of 0.59 (5) and 0.41 (6).

2-Amino-5-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), the hydrogen phthalate anion is essentially planar, with a maximum deviation of 0.011?(2)?Å. In the crystal structure, the protonated N atom of the pyridine ring and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the hydrogen phthalate anion, there is a very strong, almost symmetric, intra-molecular O-H?O hydrogen bond, generating an S(7) motif [O?O = 2.382?(3)?Å]. Furthermore, these two molecular motif rings are connected by a bifurcated N-H?(O,O) hydrogen-bonded motif R(1) (2)(4), forming a supra-molecular ribbon along the b axis. The crystal structure is further stabilized by ?-? inter-actions between the cations and anions [centroid-centroid distance = 3.6999?(10)?Å].

2-Amino-4-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), the anion is stabilized by an intra-molecular O-H?O hydrogen bond, which generates an S(7) ring motif. In the crystal, the cations and anions are linked to form extended chains along [001] by O-H?O and N-H?O hydrogen bonds. Adjacent chains are crosslinked via C-H?O inter-actions into sheets lying parallel to (100).

2-Amino-6-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), an intra-molecular O-H?O hydrogen bond occurs within the anion, thereby generating an S(7) ring, which may correlate with the fact that both the carb-oxy-lic acid and carboxyl-ate groups are almost coplanar with their attached rings [dihedral angles = 2.9?(3) and 5.2?(3)°, respectively]. In the crystal, each cation is linked to its adjacent anion by two N-H?O hydrogen bonds; the dihedral angle between the pyridine and benzene rings is 2.22?(10)°. The ion pairs are linked by further N-H?O inter-actions.

Project description:In the structure of the title salt, C(12)H(10)N(3)O(4) (+)·C(7)H(3)N(2)O(7) (-), the cations and the anions are linked by a single N(+)-H?O(carbox-yl) hydrogen bond, the discrete cation-anion unit having no inter-molecular associations other than weak cation-anion aromatic ring ?-? inter-actions [ring centroid separation = 3.7320?(14)?Å] and a number of weak inter-unit aromatic C-H?O contacts. An intramolecular C-H?O hydrox-yl-carboxyl hydrogen bond occurs in the anion.

Project description:In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36?(10) and 4.86?(11)°. The anion is stabilized by an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H?O and C-H?O inter-actions and are further consolidated by C-H?? inter-actions, to generate a three-dimensional network. A short O?N contact of 2.876?(2)?Å also occurs.
