In the title compound, 2C 3 H 7 NO 2 .H + ΓNO 3 Γ , both the alanine residues, related by a center of symmetry, are linked by a strong symmetric OΓHΓ Γ ΓO hydrogen bond with an OΓ Γ ΓO distance of 2.467 (2) A Γ . The N atom and one of the O atoms of the nitrate anion lie on the twofold axis.

Oxidation of L-proline by bis(hydrogen periodato)argentate(III) complex anion, [Ag(HIO 6 ) 2 ] 5-, has been studied in aqueous alkaline medium in the temperature range of 25-40 β by use of conventional spectrophotometry. Under the conditions for kinetic measurements, the oxidation results in decarbo
The Raman and infrared absorption spectra of 2(C 5 H 14 N 2 O 2 2+ )β’Cl -β’NO 3 -β’SO 4 2-crystal containing three anions were recorded at room temperature and were interpreted in the light of crystal structure data. The presence of a carbonyl group was identified. The carboxylic group was found to ex
