The reaction of silver hexafluoridoantimonate with Ph2PCH2PPh2NSiMe3 (1) in dichloromethane produces the dimeric complex [Ag(-Ph2PCH2PPh2NSiMe3)](2)[SbF6](2) (2), in which two heterobifunctional ligands 1 in the dication are N, P-chelated in a head-to-tail fashion to a [Ag center dot center dot center dot Ag](2+) unit that exhibits an Ag center dot center dot center dot Ag contact of 2.8530(6) angstrom. Quantum theory of atoms-in-molecules (QTAIM) analysis of the bonding revealed an attractive interaction between the two silver atoms.
