TL;DR: It is shown that phosphine ligands selectively facilitate protonation of binuclear silver hydride cations, [LAg2(H)]+ by optimizing the geometry of the active site, a key step in the selective, catalysed extrusion of carbon dioxide from formic acid, HO2CH.

TL;DR: This work reports on the serendipitous MSbased discovery of a novel silver hydride cluster, [Ag3HClL3] + (L = bis(phosphino) ligand), which has prompted its massspectrometry-directed synthesis and X-ray and neutron crystallographic structural characterization, which reveal a {Ag3(m3-H)( m3-Cl)} + core structure.

TL;DR: A bis(diphenylphosphino)methane-ligated trinuclear silver hydride nanocluster, featuring three silver(I) ions coordinated to a μ3-hydride, and its deuteride analogue, have been isolated and structurally characterized using electrospray ionization mass spectrometry, X-ray crystallography, NMR and IR spectroscopy.

TL;DR: Gas-phase reactivity of the copper hydride anions [CuH2]- and [Cu2H3]- toward a range of neutral reagents has been examined via multistage mass spectrometry experiments in conjunction with isotope labeling studies and Density Functional Theory calculations, suggesting that reactivity is mainly controlled by the acidity of the substrate.

TL;DR: In solution, mass spectrometric and small-angle X-ray scattering studies confirm maintenance of the structure of the polyanions of 2, while circular dichroism demonstrates that the chirality is also maintained.
