Abstract Contrary to the reports on the coordination oi copper (I) to N/P-ambidentate cyclotri-phosphazenes, gold (I), gold (III) and dimethylgoldf 111) chloride are found to become exclusively P-coordinated to the prototype ligand 2-methyl-4,4,6,6-tetraphenylcyclotri-phosphazene (1). The P-H proton is transferred to an adjacent nitrogen atom of the heterocycle. According to temperature dependent NMR spectra, the AuCl and the AuCl3 complexes are fluxional molecules or ions, resp., with a rapid proton transfer between P-NH-P and P = N-P functions. The behaviour is similar to that of related palladium and platinum complexes, reported previously.
