文摘

The three novel guanylurea salts with sulphuric and selenic acid are prepared and characterised. The assignment of vibrational spectra is based on crystallographic study and quantum-chemical calculations. The detailed study by vibrational spectroscopic methods of observed reversible isostructural phase transformation.
