• In this article, I introduced some new metallic germanides with electropositive elements. Those compounds have covalent Ge networks such as a three dimensional tunnel structure (LaGe5), one dimensional chains of face-shared elongated Ge6 octahedra (BaGe3), and discrete Ge3 triangle units (LaGe3). The germanides showed some characteristics of Zintl type compounds, but the electrical resistivity measurements revealed that they were metallic. I made a comparison between those metallic compounds and classical Zintl phases. The electronic structures of the metallic germanides were discussed in terms of the orbital interaction between host (germanium) and guest (electropositive elements) atoms.
