Ammonium benzenephosphonate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2008
In the crystal structure of the title salt, NH(4) (+).[(C(6)H(5))P(O)(2)(OH)](-) or NH(4) (+)·C(6)H(6)O(3)P(-), the N and O atoms inter-act via hydrogen bonds to generate a layer motif. The phenyl rings are stacked above and below this layer, sandwiching the hydrogen-bonded layer.

Ammonium Toxicity in Bacteria [PDF]

open access: yesCurrent Microbiology, 2006
Although an excellent nitrogen source for most bacteria, ammonium was-in analogy to plant and animal systems-assumed be detrimental to bacteria when present in high concentrations. In this study, we examined the effect of molar ammonium concentrations on different model bacteria, namely, Corynebacterium glutamicum, Escherichia coli, and Bacillus ...

DENSITIES OF AMMONIUM FLUORIDE-AMMONIUM NITRATE-AMMONIUM HEXAFLUOZIRCONATE SOLUTIONS [PDF]

open access: yes, 1960
The densities of various Zirflex-type solutions at 25 gas-cooled C can be expressed by the equation: p calc = (0.99710 + 0.03l57 m) + (0.02046 - 0.002659 m)c -(0.0033460.000703 m)c3/2 + 0.14349x + 0.49z where m = moles liter/ sup -1/ NH/sub 4/NO/sub 3/, c = moles liter/sup -1/ NH/sub 4/F, x = moles liter/ sup -1/ (NH/sub 4/)/sub 2/ZrF/sub 6/, and z ...

THE TORSIONAL VIBRATIONS OF THE AMMONIUM IONS IN AMMONIUM IODIDE AND AMMONIUM BROMIDE [PDF]

open access: yesChemistry Letters, 1973
Abstract The far-infrared spectra of NH4I and NH4Br have been measured at temperatures of −223 to −53 °C. The torsional vibrations of the NH4+ ions in the phase III crystalline salts were observed at 301 cm−1 for NH4I at −223 °C and at 348 cm−1 for NH4Br at −166 °C.
