dc.description.abstractA bis(diphenylphosphino)methane-ligated trinuclear silver hydride nanocluster, [Ag3((Ph2P)2CH2)3(μ3-H)](BF4)2, featuring three silver(I) ions coordinated to a μ3-hydride, and its deuteride analogue, [Ag3((Ph2P)2CH2)3(μ3-D)](BF4)2, have been isolated and structurally characterized using electrospray ionization mass spectrometry (ESI-MS), X-ray crystallography, NMR and IR spectroscopy. The position of the deuteride in [Ag3((Ph2P)2CH2)3(μ3-D)](BF4)2 was determined by neutron diffraction. ESI-MS of [Ag3L3(μ3-H/D)](BF4)2 [L = ((Ph2P)2CH2)2] produces [Ag3L3(μ3-H/D)]2+ and [Ag3L3(μ3-H/D)(BF4)]+. A rich gas-phase ion chemistry of [Ag3L3(μ3-H/D)]2+ is observed under conditions of collision-induced dissociation (CID) and electron-capture dissociation (ECD). CID gives rise to the following complementary ion pairs: [Ag3L2]+ and [L+(H/D)]+; [Ag2(H/D)L2]+ and [AgL]+; [Ag2(H/D)L]+ and [AgL2]+. ECD gives rise to a number of dissociation channels including loss of the bis(phosphine) ligand, fragmentation of a coordinated bis(phosphine) ligand via C–P bond activation, and loss of a hydrogen (deuterium) atom with concomitant formation of [Ag3L3]+. Under CID conditions, [Ag3L3(μ3-H/D)(BF4)]+ fragments via ligand loss, the combined loss of a ligand and [H,B,F4], and cluster fragmentation to give [Ag2(BF4)L2]+ and [Ag2(L-H)L]+ [where (L-H) = (Ph2P)2CH–]. © 2014, American Chemical Societyen_AU
