CePdGa$_{6}$ Structure: AB6C_tP8_123_a_hi_b-001
Other compounds with this structure
LaPdGa$_{6}$, SrAu(Au$_{0.5}$Ga$_{0.5}$)$_{2}$Ga$_{4}$
- The Springer Materials website gives SrAu(Au$_{0.5}$Ga$_{0.5}$)$_{2}$Ga$_{4}$ as the prototype, but we have chosen to use the stoichiometric CeGa$_{6}$Pd version.
