The triazenide complex of Pt(II) trans-(o-Tol)Pt(PEt3)(2)N3Ar2 (1) ( A
r = p-FC6H4) was synthesized by reaction of (o-Tol)Pt(PEt3)(2)BF4 with
Ar2N3Na. The H-1, F-19 and P-31 NMR spectra of this complex in toluen
e-d(8) were studied at different temperatures. Two kinds of dynamic pr
ocesses were observed. The first one is the intramolecular N,N' migrat
ion of the (o-Tol)Pt(PEt3)(2) group, detected by F-19 NMR. The second
process, revealed by H-1, F-19 and P-31 NMR, is the relation around th
e partially double N(2)-N(3) bond. Thermodynamic parameters for these
processes were calculated from dynamic NMR spectra. (C) 1998 Elsevier
