Abstract :

 The interactions between Ruthenium polypyridyl coordination compounds Ru (NN)32+ (N= 1,10 phenanthroline (phen), 4,7–dimethyl 1,10–phenanthroline(dmphen) and 4,7 diphenyl 1,10–phenanthroline(dpphen) and 1,4–benzoquinone(BQ) in aprotic solvent have been investigated using electrochemical method. Results indicate that there is an obvious interaction equiliium between Ru(NN)32+ and BQ. In this work, it is considered that charged molecules such as the semiquinone (Q1‒ )and the benzoquinone dianion (Q2‒ ) interact with Ruthenium II complexes through consecutive association steps. The quantitative data was obtained by calculating the thermodynamic association constants and the number of Ru(II)complex associated with both semianion and dianion of the quinone.
