摘要：

[Ga5]7− trigonal bipyramids and (M6N)9+ octahedra are present in the crystal structures of the isotypic title compounds. The charge in these phases is balanced by two electrons in metallic states: {(M6N)9+[Ga5]7− · 2e−}. This simple model of the chemical bonding is supported by band structure calculations. A section of the hexagonal crystal structure together with a pseudo‐cubic unit cell is shown on the right. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
