Abstract

The reactions between silver salts and borohydrides produce a rich set of products that range from discrete mononuclear compounds through to silver nanoparticles and colloids. Previous studies using electrospray ionization mass spectrometry (ESI-MS) to track the cationic products in solutions containing sodium borohydride, silver(i) tetrafluoroborate and the bisphosphine ligands, L, bis(diphenylphosphino)methane (dppm) and bis(diphenylphosphino)amine (dppa) have identified the dications [Ag10H8(L)6]2+. Here we isolate and structurally characterize [Ag10H8(dppa)6](BF4)2, and [Ag10H8(dppa)6](NO3)2via X-ray crystallography. Both dications have nearly identical structural features consisting of ..
