Tribenzylphosphane sulfide (SPBn₃) reacts with [Cu(CH₃CN)₄]PF₆ in a 2:1 ratio to give [Cu(CH₃CN)(SPBn₃)₂]PF₆ whereas with [Ag(CH₃CN)₄]PF₆ in the same ratio it forms [Ag₂(SPBn₃)₃](PF₆)₂. The crystal structure of the Cu(I) complex shows it to contain discrete 3-coordinate [Cu(CH₃CN)(SPBn₃)₂]⁺ cations and [PF₆]⁻ anions with the Cu atom lying in the plane formed by the two coordinated sulfur atoms and the nitrogen from the coordinated acetonitrile molecule. The Ag complex is a dinuclear species with the one silver atom being 3-coordinate and the other 4-coordinate. Each of the SPBn₃ molecules forms a Ag–C η¹-bond with one of the aromatic rings thus blocking the coordination of further SPBn₃ ligands. The two Ag centers are linked by a bridging sulfur and a weaker interaction with carbon from the aromatic ring of the same tribenzylphosphane sulfide.
