The presence of N,N-dimethylbiguanidium ion for all derivatives was evidenced by IR and 1H NMR spectra. Thermal analysis gave information on their decomposition steps and also on the accompanying thermodynamic effects. According to TG and DTG curves processes as melting, oxidative degradation as well as oxidative condensation of -C=N- units occur. The different nature of the anions results different melting points. Paracyanide formation at various condensation degrees was observed.
