摘要

The X-ray structural analysis of di-L-valine selenate monohydrate has been carried out (P2_1, a=6.181(2), b=l8.675(3), c=15.342(4) A,β=90.14(2)° V=1770.8(7) A~3, Z=4, R=0.0532 for 3057 observed reflections). The crystal structure is formed by selenate anions, L-valinium cations and water molecules (in the ratio of 1:2:1) interconnected by a system of hydrogen bonds. The FTIR (298-90 K temperature range) and FT Raman spectra were recorded and interpreted. DSC measurements were carried out in the temperature range 95-363 K. Quantitative SHG measurements of di-L-valine selenate monohydrate and tri-L-valine selenate were carried out on powdered samples.
