The asymmetric unit of the title salt, 2C6H5CH2NH3 (+)·H2P2O7 (2-), contains two independent benzyl-ammonium cations and a di-hydrogen diphosphate dianion. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the cations and anions, forming a two-dimensional network parallel to (010). Within this network, weak C-H⋯O hydrogen bonds are observed.

Streptomyces sioyaensis, which produces the antibiotic siomycin, oxidizes elemental sulfur when added to the culture medium and accumulates thiosulfate in the fermented broth. The accumulated thiosulfate was isolated as the ammonium salt and was identified by melting point, IR spectrum, and paper chromatography. A variety of other streptomycetes also oxidized elemental sulfur and accumulated th...

A simple, efficient and eco-friendly procedure for the selective monohydrolysis of diethyl 2,6-dimethyl-4-aryl-4H-pyran-3,5-dicarboxylates under quaternary ammonium salt catalysis conditions is presented. The catalytic activities of various quaternary ammonium salts were investigated using different molar ratios of NaOH and water-organic solvent mixtures. The results indicate that the combinati...

Light-absorbing and high-molecular-weight secondary organic products were observed to result from the reaction of glyoxal in mildly acidic (pH=4) aqueous inorganic salt solutions mimicking aqueous tropospheric aerosol particles. High-molecular-weight (500–600 amu) products were observed when ammonium sulfate ((NH4)2SO4) or sodium chloride (NaCl) was present in the aqueous phase. The products fo...

A bolaamphiphilic low-molecular-weight gelator based on crown ether, which could self-assemble into organogels and hydrogels, was prepared. The contribution of each part of the structure to the gelation property was investigated by designing a series of analogues. A simple framework (crown ether-hydrophobic linkage-ammonium salt) was proposed.

The reaction between benzyl-triethyl-ammonium chloride and dimethyl-tin dichloride yields the title salt, [(C(6)H(5)CH(2))(C(2)H(5))(3)N](2)[SnCl(6)]. The Sn(IV) atom, located on a center of inversion, exists in an octa-hedral coordination environment. The cation links with the anion via weak C-H⋯Cl hydrogen bonding.

In the title molecular salt, C(10)H(15)NH(3) (+)·C(7)H(5)O(2) (-), both carboxyl O atoms act as acceptors for strong N-H⋯O inter-molecular hydrogen-bond inter-actions with the ammonium group in the cation, generating infinite chains along the b axis. A weak C-H⋯π inter-action is also present.
