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

ABSTRACT: 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.

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⋯π inter-actions, to generate a three-dimensional network. A short O⋯N contact of ...[more]

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].

Bis(1,10-phenanthroline-5,6-dione-?N,N')silver(I) 2-hy-droxy-3,5-dinitro-benzoate.

Project description:In the cation of the title salt, [Ag(C(12)H(6)N(2)O(2))(2)](C(7)H(3)N(2)O(7)), the Ag(I) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitro-salicylate anion has only a short contact [2.847?(6)?Å] between one of its O atoms and the Ag(I) atom. 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.

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

Project description:The title compound, a Schiff base, C(24)H(31)NO(3), has a substituted aromatic ring at both ends of the azomethine linkage and these make a dihedral angle of 24.9?(1)°. There is an intra-molecular hydrogen bond between the hy-droxy group (donor) and the N atom of themazomethine linkage.

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.

Poly[(μ-2-hy-droxy-3,5-dinitro-benzoato)rubidium].

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(7))](n), comprises an Rb(+) cation and a 3,5-dinitro-salicylate ligand. The Rb(+) cation is 10-coordinated by O atoms from eight 3,5-dinitro-salicylate anions and is linked by three μ(2)-O atoms, forming a zigzag chain along the b-axis direction, which is further linked by the phenyl groups, giving the three-dimensional framework. The crystal structure involves intra-anionic O-H⋯O hydrogen bonds and strong π-π stacking inter-actions [centroid-centroid distance = 3.6755 (7) Å].

2-Amino-4,6-dimethyl-pyrimidinium 3,5-dinitro-benzoate dihydrate.

Project description:In the title compound, C(6)H(10)N(3) (+)·C(7)H(3)N(2)O(6) (-)·2H(2)O, the amino-pyrimidine mol-ecule is protonated at one of the pyrimidine N atoms. The carboxyl-ate group of the 3,5-dinitro-benzoate anion inter-acts with the protonated pyrimidine N atom and the 2-amino group through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) motif. Two inversion-related pyrimidine rings are linked via a pair of N-H⋯N hydrogen bonds, also forming an R(2) (2)(8) ring motif.

Phenyl 3,5-di-tert-butyl-2-hy-droxy-benzoate.

Project description:The title mol-ecule, C(21)H(26)O(3), has a six-membered planar carbon ring as the central core, substituted at position 1 with phen-oxy-carbonyl, at position 2 with hy-droxy and at positions 3 and 5 with tert-butyl groups. The structure shows two independent but very similar mol-ecules within the asymmetric unit. For both independent mol-ecules, the ester carboxyl-ate group is coplanar with the central core, as reflected by the small C-C-O-C torsion angles [179.95?(17) and 173.70?(17)°]. In contrast, the phenyl substituent is almost perpendicular to the carboxyl-ate -CO(2) fragment, as reflected by C-O-C-C torsion angles, ranging from 74 to 80°. The coplanarity between the central aromatic ring and the ester carboxyl-ate -CO(2)- group allows the formation of an intra-molecular hydrogen bond, with O?O distances of 2.563?(2) and 2.604?(2)?Å.
