Dinuclear osmium(IV) oxo complexes with a dithioimidodiphosphinate ligand

The protonation of trans-[Os(OMe)2{N(Pri2PS)2}2] (1) with HBF4, followed by treatment with NH3(g) afforded the oxo-bridged dimer [Os2(μ-O){N(Pri2PS)2}4F2] (2). Reaction of 2 with Ag(OTf) (OTf− = triflate) gave the heterometallic Os(IV)/Ag(I) complex [Os2(μ-O){N(Pri2PS)2}4F2(AgOTf)2] (3), in which each Ag(OTf) moiety binds to three sulfur atoms of the [N(Pri2PS)2]− ligands.47
