A new method for synthesizing proton transfer compound [pyda center dot H(2)](2+)[pydc](2-) from 2,6-pyridinedicarboxylic acid (pydc center dot H(2)) and 2,6-pyridinediamine (pyda) was explored under ultrasonic. Some factors on the yields of proton transfer compound [pyda center dot H(2)](2+)[pydc](2-) were investigated including different solvents, reaction time and reactant concentration. The results indicated that the proton transfer compound [pyda center dot H(2)](2+)[pydc](2-) could be synthesized in different types of solvents within a relatively short time under ultrasonic. The synthetic method was very convenient without catalyst and heating but short reaction time and high yield.
