Vibrational spectroscopic and crystallographic study of the novel guanylurea salts with sulphuric and selenic acids
Original language description
The family of known guanylurea(1+) sulphates was extended for two novel triclinic (space group P-1) members bis(guanylurea(1+)) sulphate dihydrate and tetrakis(guanylurea(1+)) bis(hydrogen sulphate) sulphate. Additionally, the monoclinic (space group P2(1)/n) guanylurea(1+) hydrogen selenate was also isolated and characterised. Besides of X-ray diffraction study these novel guanylurea chalcogenates were studied by the methods of vibrational spectroscopy. The study of thermal behaviour of the prepared salts revealed reversible lambda-shaped anomaly for tetrakis(guanylurea(1+)) bis(hydrogen sulphate) sulphate at 354 K. This effect was studied in detail by the combination of DSC and temperature-dependent IR and Raman spectroscopies.
