ChemInform Abstract: Isolated Hexagonal Channels Built Up by Three-Connected Ge- Ions in LiGe at High Pressure.

At 4 GPa and 900°C, hexagonal high-pressure LiGe—a Zintl phase—with a new structural motif was prepared: isolated hexagonal channels built up by three-coordinate Ge− ions. These channels consist of puckered germanium six-membered rings of distorted chairs and boats (see picture). Li+ counterions are found in the centers of the channels and in the symmetry-equivalent positions between the channels.
