Abstract

Electrospray ionisation mass spectrometry (ESI-MS) was used to monitor the reaction of AgBF4, bis(diphenylphosphino)amine (dppa = (Ph2P)2NH = LPh) and NaBH4 in acetonitrile and thereby direct the synthesis of the silver nanocluster [Ag3(μ3-H)(μ3-BH4)LPh3](BF4), 3b·BF4, formed via reaction of AgBF4, bis(diphenylphosphino)amine (dppa = (Ph2P)2NH = LPh) and NaBH4 in acetonitrile. The X-ray structure of 3b·BF4 highlights that the cation adopts a planar trinuclear Ag3 geometry surrounded by three dppa ligands and coordinated on the bottom face by a μ3-hydride and on the top face by a μ3-BH4. The solution phase structure of 3b·BF4 was characterised by multinuclear NMR and DOSY NMR, which showed th..
