Abstract

[Tris(dimethylamino)phosphane]gold(I) chloride, μ‐tris‐{[tris(dimethylamino)phosphane]gold(I)}oxonium tetrafluoroborate, {μ~3~‐tris(dimethylamino)phosphaneimidotris[tris(dimethylamino)phosphane]gold(I)}(2+) bis(tetrafluoroborate) and N‐trimethylsilyltris(dimethylamino)phosphaneimine were prepared using modifications of established procedures. Their structures were determined in single‐crystal X‐ray diffraction studies. The ligand (Me~2~N)~3~P, here introduced into gold(I) chemistry for the first time, lends high stability to these compounds through efficient steric shielding of the reaction sites and through a balanced electronic substituent effect. The structural details of the (Mr~2~N)~3~P groups are of current interest because of the unusual nonequivalent configuration of the nitrogen atoms in the dimethylamino groups. This behaviour has been observed for most of the (Me~2~N)~3~P units in the compounds studied in this work.
