In the structure of the title compound, [Li(C(5)H(4)N(2)O(2))(NO(3))](n), the Li(I) ion is coordinated by two carboxyl-ate O atoms donated by two ligands and two nitrate O atoms in a distorted tetrahedral geometry. Li(I) ions, bridged by carboxyl-ate O atoms, form mol-ecular ribbons composed of dimeric units. Two nitrate O atoms link the ribbons into mol-ecular layers parallel to (001). Hydroge...

The N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(CH(3)COO)(2)(NO(3))(4)], exist in the zwitterionic form. One heterocycle binds to a metal center whereas the other bridges two metal centers. Each La atom is chelated by an acetate and two nitrate groups and is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic coordination environment. The N-H ...

The title compound, [Ag(NO(3))(C(20)H(30)S(2))](n), was synthesized by the reaction of silver nitrate and 1,4-bis-(cyclo-hexyl-thio-meth-yl)benzene (bctmb) in acetonitrile. The coordination polymer exhibits a two-dimensional layer structure. The layers are wave-like and parallel to the crystallographic ac plane; Ag(I) ions are linked by the bctmb ligands and nitrate anions along the crystallogr...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 2009...

This work is devoted to a study of the structural changes in a single crystal of ammonium nitrate, NH4NO3, doped with copper(II) cations by electron paramagnetic resonance. Ammonium nitrate crystallizes at atmospheric pressure in several polymorphic forms, phase VII → V → IV → III → II → I → melt, with transition temperatures of 103 K, 255 K, 305 K, 357 K, 398 K, and 443 K, respectively. The ai...

Yttrium aluminum garnet nanoparticles both undoped and doped with lanthanide ions (Ce, Eu, Dy and Tb) having average size around 30 (73nm) nm were prepared by glycine nitrate combustion method followed by annealing at a relatively low temperature of 800 1C. Increase in the annealing temperature has been found to improve the luminescence intensity and for 1200 1C heated samples there exists stro...

Induction, energy gain, effect on growth, and interaction of nitrate and nitrite reduction of Bradyrhizobium sp. (Lupinus) USDA 3045 were characterized. Both nitrate and nitrite were reduced in air, although nitrite reduction was insensitive to ammonium inhibition. Anaerobic reduction of both ions was shown to be linked with energy conservation. A dissimilatory ammonification process was detect...

Sputtering of condensed-phase ammoniumnitrate yields an extensivedistribution of negative cluster ions of the form [(NH4N03),N03]-, n 2 3. Collision-induced dissociation of mass-selected cluster ions suggests that the first two members of the series, n = 1 and n = 2, are missing because the ions rearrange to lose one or more ammonia molecules. Gradient-corrected density-functional calculations ...

We report on the photoconductive response of nanostructured sol-gel films in function of the silver nitrate concentration (ions and colloids). Silver colloids were obtained by spontaneous reduction process of Ag+ ions to Ag(0). 2-d hexagonal nanosructured sol-gel thin films were prepared by dip-coating method using the non-ionic diblock copolymer Brij58 to produce channels into the film, which ...
