The interionic structure in methylene chloride of trans-[Ru(PMe3)(2)(CO)(CO
Me)(CH2-pz(2))]BPh3R (where pz = pyrazolyl ring; R = Me, n-Bu, n-Hex and Ph
) complex es has been investigated by the detection of interionic contacts
in H-1 NOESY NMR spectra. We observed an unexpected specificity of interion
ic contacts that allowed, for the first time, the estimation of reasonable
average interionic distances by measuring the kinetic of H-1 NOE buildup.
