The crystals of a new melaminium salt, i.e. melaminium butyrate were obtained by slow evaporation of an aqueous solution at room temperature. The room temperature powder infrared and R'aman measurements were carried out. DSC measurements clearly point to the occurrence of the phase transition of the first order at ca, 239 K. No detectable signal was observed during powder test for second harmonic generation.
