2-(2,4-Dinitro-benz-yl)pyridinium 2-hy-droxy-3,5-dinitro-benzoate.

ABSTRACT: 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.

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 π-π 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. ...[more]

2-Hy-droxy-anilinium 3,5-dinitro-benzoate.

Project description:In the title molecular salt, C(6)H(8)NO(+)·C(7)H(3)N(2)O(6) (-), which crystallizes in the chiral monoclinic space group P2(1), the achiral components assemble by three different N-H⋯O, one O-H⋯O and one C-H⋯O hydrogen bonds into two-stranded chains running parallel to [010]. The dihedral angles between the carboxy group and the two nitro groups and the mean plane of their attached benzene ring are 24.5 (9), 6.1 (6) and 13.0 (1)°, respectively..

Ethyl 4-[(3,5-di-tert-butyl-2-hy-droxy-benz-yl)amino]-benzoate.

Project description:The title amine, C(24)H(33)NO(3), has two substituted aromatic rings at either end of the -CH(2)NH- linkage [C(ar-yl)-CH(2)-NH-C(ar-yl) torsion angle = 77.4 (3)°]. The amino and hy-droxy groups are hydrogen-bond donors to the carbonyl O atom of an adjacent mol-ecule. These hydrogen bonds give rise to a chain that runs along the b axis. One of the tert-butyl groups is disordered over two positions with a site-occupation factor of 0.834 (6) for the major occupied site.

2-Amino-4-methylpyridinium 2-hy-droxy-3,5-dinitro-benzoate.

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.

Di-n-butyl-ammonium 2-[(3,5-di-tert-butyl-4-hy-droxy-benz-yl)sulfan-yl]benzoate.

Project description:The title salt, C(8)H(20)N(+)·C(22)H(27)O(3)S(-), is a proton-transfer compound derived from the recently reported parent carb-oxy-lic acid [Alhadi et al. (2010). Acta Cryst. E66, o1787] by the addition of a second equivalent of di-n-butyl-amine, yielding the di-n-butyl-ammonium carboxyl-ate salt. The structure of the carboxyl-ate anion resembles that of the parent carb-oxy-lic acid. The main difference lies in the position of the H atom in the 4-hy-droxy group. In the anion the O-H bond is perpendicular, rather than parallel, to the benzyl ring. This position appears to facilitate hydrogen bonding to an O atom of the carboxyl-ate group of a symmetry-related anion. In addition, there are three N-H⋯O hydrogen bonds. In contrast, the neutral species hydrogen bonds via a carboxylic acid dimer. The dihedral angle between the benzene rings in the anion is 79.19 (7)°.

4-[(2-Hy-droxy-benz-yl)amino]-pyridinium nitrate.

Project description:The planes of the aromatic rings in the cation of the title salt, C(12)H(13)N(2)O(+)·NO(3) (-), are twisted along the -CH(2)-NH- single bond by 75.3 (1)°. In the crystal, the phenol O, amine N and pyridinium N atoms are hydrogen-bond donors to the O atoms of the nitrate counter-ions. These hydrogen bonds lead to the formation of a layer in the crystal.

Bis[2-(2,4-dinitro-benz-yl)pyridinium] biphenyl-4,4'-disulfonate trihydrate.

Project description:In the structure of the title salt, 2C(12)H(10)N(3)O(4) (+)·C(12)H(8)O(6)S(2) (2-)·3H(2)O, determined at 173?K, the biphenyl-4,4'-disulfonate dianions lie across crystallographic inversion centres with the sulfonate groups inter-acting head-to-head through centrosymmetric cyclic bis-(water)-bridged hydrogen-bonding associations [graph set R(4) (4)(11)], forming chains. The 2-(2,4-dinitro-benz-yl)pyridinium cations are linked to these chains through pyridinium-water N-H?O hydrogen bonds and a two-dimensional network is formed through water bridges between sulfonate and 2-nitro O atoms, while the structure also has weak cation-anion ?-? aromatic ring inter-actions [minimum ring centroid separation = 3.8441?(13)?Å].

The dihedral angle between the two 1,10-phenanthroline-5,6-dione ligands is 58.4?(1)°. There is an intra-molecular O-H?O hydrogen bond in the 3,5-dinitro-salicylate anion.

2-Amino-3-(hy-droxy-meth-yl)pyridinium 2-benzoyl-benzoate monohydrate.

Project description:In the title hydrated salt, C(6)H(9)N(2)O(+)·C(14)H(9)O(3) (-)·H(2)O, the dihedral angle between the benzene rings of the 2-benzoyl-benzoate anion is 82.04 (14)°, while the angles between the aromatic ring of the pyridinium cation and each of the benzene rings of the anion are 4.42 (14) and 82.04 (14)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a three-dimensional network with R(2) (2)(8), R(6) (6)(16) and R(4) (4)(6) motifs. The crystal packing is further stabilized by two π-π inter-actions, one between pyridinium rings, and another between the benzene benzoate and pyridinium rings of neighbouring mol-ecules, with centroid-to-centroid distances of 3.559 (2) and 3.606 (2) Å, respectively.

Project description:In the salicylate anion of the title salt, C(5)H(7)N(2) (+)·C(7)H(5)O(3) (-), an intra-molecular O-H?O hydrogen bond generating an S(6) ring motif is observed. In the crystal structure, the cations and anions are linked into a two-dimensional network parallel to the ab plane by N-H?O and C-H?O hydrogen bonds. The network contains R(2) (2)(7) and R(1) (2)(4) ring motifs. Weak ?-? inter-actions between the benzene and pyridinium rings [centroid-centroid distance = 3.688?(1)?Å] are also observed.
