This work presents the different coordination nature of the bidentate ligand towards gold and silver complexes. The reaction of 1 with AuClSMe2 in dichloromethane resulted in two gold atoms containing six-membered ring PhC(NtBu)2Si-Au⋯Au-PPh2C6H4 (2). Compound 2 exhibits intramolecular aurophilic interaction (2.9987(7) Å), which is further supported by quantum chemical calculations. Moreover, the reduction of aluminium adduct 3 with AgSbF6 affords insertion of silver cation [{PhC(NtBu)2SiF2}-C6H4(PPh2)-Ag-(PPh2)C6H4{PhC(NtBu)2SiF2}]AlCl4- (4) between two phosphane. In compound 4 only two P(III) of two molecules of 1 coordinates to Ag(I), while two Si(II) remains uncoordinated and gives oxidative addition of Fluorine.
