摘要：

Isolated and complex: La2MgNi2H8 contains isolated dinuclear [Ni2H7]7- and tetranuclear [Ni4H12]12- anions (see picture). These are the first polynuclear solid-state nickel hydride complexes. Their formation upon hydrogenation of the intermetallic compound La2MgNi2 is associated with a metal-insulator transition. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
