The preparation of tri(alkynyl)gold(III) complexes (RC≡C) 3Au(L) as metastable compounds was discussed. It was found that the complex can be prepared if a small and strong trialkylphosphine donor was introduced as an auxiliary ligand L. The complex with L = PMe3 was crystallize in a solvent-free form and as a 1:1 solvate with CH 2Cl2. The results show that the stability of polyalkynyl complexes of gold(III) centers appears to be generally lower than that of the isoelectronic platinum(II) centers.
