Isolated and complex : La 2 MgNi 2 H 8 contains isolated dinuclear [Ni 2 H 7 ] 7− and tetranuclear [Ni 4 H 12 ] 12− anions (see picture). These are the first polynuclear solid‐state nickel hydride complexes. Their formation upon hydrogenation of the intermetallic compound La 2 MgNi 2 is associated with a metal–insulator transition.
