4,6-Dinitro-pyrogallol.

ABSTRACT: In the title mol-ecule, C(6)H(4)N(2)O(7), the two nitro groups are tilted with respect to the aromatic ring by 11.2?(1) and 10.9?(1)°. All three hy-droxy groups are involved in the formation of bifurcated intra- and inter-molecular O-H?O hydrogen bonds. The crystal packing exhibits short O?O distances of 2.823?(2)?Å between two O atoms of the nitro groups.

In the title mol-ecule, C(6)H(4)N(2)O(7), the two nitro groups are tilted with respect to the aromatic ring by 11.2 (1) and 10.9 (1)°. All three hy-droxy groups are involved in the formation of bifurcated intra- and inter-molecular O-H⋯O hydrogen bonds. The crystal packing exhibits short O⋯O distances of 2.823 (2) Å between two O atoms of the nitro groups. ...[more]

4,6-Dinitro-benzene-1,3-diamine.

Project description:The mol-ecule of the title compound, C(6)H(6)N(4)O(4), is almost planar, being stabilized by two intra-molecular N-H⋯O hydrogen bonds. Further N-H⋯O links lead to a sheet in the crystal structure.

(RS)-Dimethyl-ammonium 2-sec-butyl-4,6-dinitro-phenolate.

Project description:The title compound, C(2)H(8)N(+)·C(10)H(11)N(2)O(5) (-), is a highly toxic herbicide known as dinoseb. The sec-butyl group is disordered [occupancy ratio 0.828?(3):0.172?(3)], while the nitro group in the 6 position is twisted by 25° with respect to the ring plane. Pairs of -O(-)?H-N(+)-H?(-)O- bridges between phenolic O atoms generate eight-membered hydrogen-bonded rings.

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.

2,2'-(4,6-Dinitro-1,3-phenyl-enedi-oxy)diacetic acid dihydrate.

Project description:In the title compound, C(10)H(8)N(2)O(10)·2H(2)O, the skeleton of the dicarboxylic acid mol-ecule is approximately planar, the largest deviation being 0.477?(1)?Å for an O atom of a nitro group; this nitro group is twisted out of the plane of the ring by 24.6?(1)°. Adjacent mol-ecules are linked by O-H?O hydrogen bonds, which connect the dicarboxylic acid and water mol-ecules into a three-dimensional supra-molecular network.

2-Amino-pyridinium 2-meth-oxy-carbonyl-4,6-dinitro-phenolate.

Project description:In the title mol-ecular salt, C(5)H(7)N(2) (+)·C(8)H(5)N(2)O(7) (-), the 2-amino-pyridinium cation is essentially planar, with a maximium deviation of 0.015?(1)?Å, while the 2-meth-oxy-carbonyl-4,6-dinitro-phenolate anion is slightly twisted away from planarity, with a maximium deviation of 0.187?(1)?Å. Deprotonation of the hy-droxy O atom was observed. The cation and anion are connected by four bifurcated N-H?(O,O) hydrogen bonds, forming a mol-ecular proton-transfer adduct. The dihedral angle between the pyridinium ring in the cation and the benzene ring in the anion is 3.65?(6)°. Every adduct connects to six neighboring adducts by N-H?O and C-H?O hydrogen bonds, yielding extended layers parallel to the bc plane. There is a weak ?-? inter-action between the benzene rings of two neighboring anions; the inter-planar spacing and the centroid-centroid separation are 3.309?(1) and 3.69?(1)?Å, respectively.

2-(4-Amino-benzene-sulfonamido)-4,6-dimethyl-pyrimidin-1-ium 2-carb-oxy-4,6-dinitro-phenolate.

Project description:In the structure of the phenolate salt of the sulfa drug sulfamethazine with 3,5-dinitro-salicylic acid, C12H15N4O2S(+)·C7H3N2O7 (-), the dihedral angle between the pyrimidine and benzene rings of the cation is 59.70 (17)°. In the crystal, cation-anion hydrogen-bonding inter-actions involving pyrim-idine-carb-oxy N(+)-H⋯O and amine-carb-oxy N-H⋯O pairs give a cyclic R 2 (2)(8) motif while secondary N-H⋯O hydrogen bonds between the aniline group and both sulfone and nitro O-atom acceptors give a two-dimensional structure extending in (001).

2,2'-[(4,6-Dinitro-1,3-phenyl-ene)dioxy]diacetic acid hemihydrate.

Project description:The skeletons of both independent mol-ecules of the carboxylic acid hemihydrate, C(10)H(8)N(2)O(10)·0.5H(2)O, are approximately planar [maximum deviations 0.642?(3) and 0.468?(1)?Å]. The deviations arise from the twisting of the nitro groups with respect to the aromatic rings [dihedral angles = 3.24?(2) and 27.01?(1), and 7.87?(1) and 16.37?(2)° in the two molecules]. The crystal structure features inter-molecular O-H?O hydrogen bonds, which the link the dicarboxylic acid and water mol-ecules into a supra-molecular layer network.

2-Isopropyl-6-methyl-4-oxo-3,4-dihydro-pyrimidin-1-ium 2-carb-oxy-4,6-dinitro-phenolate monohydrate.

Project description:In the title mol-ecular salt, C(8)H(13)N(2)O(+)·C(7)H(3)N(2)O(7) (-)·H(2)O, the pyrimidinium cation is essentially planar, with a maximum deviation of 0.009?(1)?Å. The cation undergoes an enol-keto tautomerism during the crystallization. In the crystal, the ion pairs and water mol-ecules are connected via O-H?O, N-H?O and C-H?O hydrogen bonds, forming two-dimensional networks parallel to the bc plane. There is an intra-molecular O-H?O hydrogen bond in the 3,5-dinitro-salicylate anion, which generates an S(6) ring motif.

Poly[(?-3,5-dinitro-benzoato)(?-3,5-dinitro-benzoic acid)rubidium].

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))(C(7)H(4)N(2)O(6))](n), comprises an Rb(+) cation, a 3,5-dinitro-benzoate anion and a 3,5-dinitro-benzoic acid ligand. The Rb(+) cation is nine-coordinated by O atoms from four 3,5-dinitro-benzoate anions and three neutral 3,5-dinitro-benzoic acid ligands. The metal atom is firstly linked by four bridging carboxyl groups, forming a binuclear motif, which is further linked by the nitro groups into a two-dimensional framework along the [110] direction. A short O-H?O hydrogen bond between two adjacent carboxy/carboxylate groups occurs.
