Coinage metal hydrides are stabilized by negative charge : Reactions of energized laser‐ablated gold, silver, and copper with H 2 in excess argon, neon, and pure normal hydrogen during condensation at 3.5 K give the MH molecules, the (H 2 )MH complexes, the MH 2 − ions, and the MH 4 − ion only for gold. The stable linear MH 2 − ions are unique in that their corresponding neutral MH 2 molecules are higher in energy and thus unstable to M + H 2 decomposition.
