The framework of the title compound, {(NH(3)CH(2)CH(2)NH(3))[CdCl(4)]}(n), is built upon layers parallel to (100) made up from corner-sharing [CdCl(6)] octa-hedra. NH(3)CH(2)CH(2)NH(3) (2+) cations are situated between the layers and are linked to the layers via an N-H⋯Cl hydrogen-bonding network. The Cd atom is located on an inversion centre and the coordination environment is described as hig...

Alkylation of [{Ti(η(5)-C(5)Me(5))(μ-NH)}(3)(μ(3)-N)] with MeOTf occurs at the imido ligands to produce the methylamido derivative [Ti(3)(η(5)-C(5)Me(5))(3)(μ(3)-N)(μ-NH)(2)(μ-NHMe)(OTf)] which readily rearranges to form the methylimido complex [Ti(3)(η(5)-C(5)Me(5))(3)(μ(3)-N)(μ-NH)(μ-NH(2))(μ-NMe)(OTf)].

Here we show that in aging Saccharomyces cerevisiae (budding yeast) cells, NH(4) (+) induces cell death associated with shortening of chronological life span. This effect is positively correlated with the concentration of NH(4) (+) added to the culture medium and is particularly evident when cells are starved for auxotrophy-complementing amino acids. NH(4) (+)-induced cell death is accompanied ...

A metathesis reaction between unsolvated NaB(3)H(8) and NH(4)Cl provides a simple and high-yield synthesis of NH(4)B(3)H(8). Structure determination through X-ray single crystal diffraction analysis reveals weak N-H(δ+)---H(δ-)-B interaction in NH(4)B(3)H(8) and strong N-H(δ+)---H(δ-)-B interaction in NH(4)B(3)H(8)·18-crown-6·THF adduct. Pyrolysis of NH(4)B(3)H(8) leads to the formation of hydr...

This study assessed the effect of race/ethnicity on the prevalence of inconsistent reports regarding ever smoking, time since smoking cessation, and age of initiating regular smoking. We used the Tobacco Use Supplement to the Current Population Survey data, which came from a test-retest reliability study, and considered three racial/ethnic subpopulations, Hispanics, Non-Hispanic (NH) Blacks and...
