摘要

The molecular self-diffusion coefficients of the complexes trans-[Ru(PMe3)(2)(CO)(COMe)(pz(2)-CH2)]BPh4 and trans-[Ru(PMe3)(2)(CO)(COMe)(pz(2)-BH2)] have been measured by pulsed field gradient spin-echo NMR measurements in nitromethane, chloroform, and methylene chloride as a function of concentration. By using the neutral complex as reference with the assumption that it does not undergo associative processes, clear indications of the presence of ions tin nitromethane), ion pairs fin chloroform at low concentration), and ion quadruples tilt chloroform at high concentration) have been obtained.
