Abstract

Two successive phase transitions in bis-n-dodecylammonim hexachlorostannate, (n-C₁₂H₂₅NH₃)₂SnCl₆, were studied by means of ¹H NMR. From the temperature dependent dipolar splitting, the low and the high temperature transition were attributed to an order-disorder transition and a conformational transition of the rigid hydrocarbon chain, respectively. The spin-lattice relaxation rate in the low and the intermediate temperature phase was well fitted with four types of molecular motions, and the ammonium group was revealed to dictate the order-disorder transition temperature.
