In calcareous soils, phosphorus (P) retention and immobilization take place due to precipitation and adsorption. Since soil pH is considered a major soil variable affecting the P sorption, an acidic P fertilizer could result in low P adsorption compared to alkaline one. Therefore, P adsorption from DAP and phosphoric acid (PA) required to produce desired soil solution P concentration was estima...

A redetermination of the crystal structure of the title compound, C(6)H(16)N(2) (2+)·2Cl(-), was undertaken. All atomic coordinates including those of the H atoms were refined freely. The cation is located on a centre of symmetry. Important for the crystal structure are wavy hydrogen-bonded layers that are formed by ammonium groups and chloride anions, giving hydrogen-bonded rings.

The title compound, (NH(4))(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2), has been obtained serendipitously. It is isotypic with the heavier alkali analogues M(2)Cd(3)(SO(4))(3)(OH)(2)(H(2)O)(2) (M = K, Rb, Cs). The structure contains two Cd(2+) ions, one in a general position and one with site symmetry m. The former Cd(2+) ion is coordinated by three O atoms of three SO(4) groups, two hydroxide O atoms ...

The X-ray crystal structure of 1,12-dodecane diammonium (C(12)DA(2+)) encapsulated in cucurbit[8]uril reveals an unconventional U-shaped conformation of C(12)DA(2+), which is attributed to the favorable host-guest interactions to overcome the charge-charge repulsion of the two ammonium groups in close proximity and high internal strain.
