Structural studies on tribenzylphosphane sulfide complexes of copper(I) and silver(I)

The bulky tertiary phosphane sulfide, SPBn3, reacts with Cu(I) to form 3-coordinate [Cu(CH3CN)(SPBn3)2]PF6 whereas with Ag(I) it forms dinuclear [Ag2(SPBn3)3](PF6)2 which contains both 3- and 4-coordinated Ag. The Ag atoms are linked by a bridging sulfur and a carbon from the aromatic ring of the same SPBn3.69
