Abstract
PGSE diffusion NMR studies on a series of mononuclear and dinuclear cationic platinum salts derived from (S)-MeO-Biphep and (R)-p-tolyl-BINAP are reported. The data show that (a) one can readily distinguish between mononuclear and dinuclear cations (b) the amount of ion pairing can be estimated qualitatively and (c) the charge delocalization rather than the amount of formal charge per metal cation is important for the position of the anion. The solid-state structure of the chloro-bridged salt, [Pt(l-Cl){(S)-MeO-Biphep}] 2(CF3SO3)2, is reported.
