2,4,6-Triamino-1,3,5-triazin-1-ium acetate acetic acid solvate monohydrate. Infrared and Raman spectra

Abstract

The crystals of the new melaminium salt, i.e. melaminium acetate acetic acid solvate monohydrate, C3H7N6+· CH3COO-·CH3COOH·H2O, were obtained by the slow evaporation of an aqueous solution at room temperature. Powder infrared and Raman spectra were measured and interpreted. The vibrational spectra in the region of internal vibrations of ions corroborate structural data recently published by Perpétuo and Janczak. Some spectral features of this new crystal are referred to corresponding one for melamine crystal as well as other melamine complexes in crystalline form. Hydrogen-bonded network present in the crystal gives notable vibrational effect.
