The asymmetric unit of the title compound, [Rb(C(6)H(3)N(2)O(5))(H(2)O)](n), comprises a rubidium cation, a 2,4-dinitro-phenoxide anion and a water mol-ecule. The Rb(+) cation is 11-coordinated by O atoms from 2,4-dinitro-phenolate anions and water mol-ecules. The metal centre is firstly coordinated by two μ(3)-H(2)O to form a one-dimensional ladder-shaped unit, [Rb(2)(μ(3)-H(2)O)(2)], which is...

The title compound, C(13)H(9)N(5)O(6), contains three nitro groups. It is prepared by the reaction of benzaldehyde 2,4-dinitro-phenyl-hydrazone with nitric oxide at ambient temperature. The imine group is nearly coplanar with the (2,4-dinitro-phen-yl)-hydrazine unit. The second benzene ring and the third nitro group are twisted away from this plane, with dihedral angles of 48.5 (3) and 15.2 (3)...

Strontium-based red pyrotechnic colorants have fallen into disrepute due to the harmful influence of this alkaline earth metal on adolescents. In context, energetic character, safety, and combustion benign nitrogen gas nitropyrazoles are used for design corresponding lithiated materials, which investigated as potential replacements in current work. For purpose, lithium salts 3,4-dinitro-1H-pyra...

In the title compound, C(10)H(10)N(4)O(5)S·C(9)H(9)N(3)O(5), the amide groups of 3-(3,5-dinitro-benzo-yl)-1,1-dimethyl-thio-urea and N,N-dimethyl-3,5-dinitro-benzamide mol-ecules are oriented at dihedral angles of 39.13 (8) and 55.97 (11)°, respectively, to the attached benzene rings. In the crystal, the two mol-ecules are linked by an N-H⋯O hydrogen bond. Weak C-H⋯O link the mol-ecules into a ...

Crystals of the title compound, C(12)H(10)N(4)O(5), were obtained from a condensation reaction of 2,4-dinitro-phenyl-hydrazine and 2-furyl methyl ketone. The mol-ecule displays a nearly planar structure, and the furan ring is slightly twisted by a dihedral angle of 12.62 (6)° with respect to the phenyl-hydrazone plane. The face-to-face separation of 3.287 (7) Å between parallel benzene rings of...

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...

Flavin and pyridine nucleotide fluorescence was continuously monitored from the surface of the hemoglobin-free, perfused rat liver with the use of a new double fluorometer. In response to anoxia or after addition of inhibitors of the respiratory chain, the fluorescence intensity excited at 436 rnk decreased, while that excited at 366 rnb increased, representing reduction of flavin and pyridine ...

A new general approach to double nitration of 6,12-di(hetero)aryl-substituted and 6,12-unsubstituted 5,11-dialkyl-5,11-dihydroindolo[3,2-b]carbazoles by acetyl nitrate has been developed to obtain their 2,8-dinitro and 6,12-dinitro derivatives, respectively. A formation of mono-nitro derivatives (at C-2 or C-6) from the same indolo[3,2-b]carbazoles has also been observed in several cases. Reduc...

The ozonation of trifluralin coated on azelaic acid particles is investigated with a vacuum ultraviolet photoionization aerosol time-of-flight mass spectrometer. The suspended trifluralin particles with the mean diameter of 270nm react with approximately 100ppm ozone in an aerosol reaction chamber under ambient pressure and room temperature (1atm, 298K). The time-of-flight mass spectra of the t...
