摘要：

Preparation, crystal and molecular structure as well as vibrational spectra of the crystal L-alanine L-alaninium picrate monohydrate are described. The title crystal is monoclinic, space group P2(1). The asymmetric unit contains one dimeric (L-Ala...L-Ala(+)) cation, one picrate anion and a water molecule. The O center dot center dot center dot O distance in the dimeric cation is equal to 2.553(2)angstrom. The IR and Raman spectra are interpreted based on the structure. (C) 2012 Elsevier B.V.
