Ternary clathrates Ba–Zn–Ge: phase equilibria, crystal chemistry and physical properties

Abstract

The formation, phase relations, crystal chemistry and physical properties were investigated for the solid solution deriving from binary clathrate with a solubility limit of 8 Zn atoms per formula unit at 800 °C ( is a vacancy). Single-crystal x-ray data throughout the homogeneity region confirm the clathrate type I structure with cubic primitive space group type .
