On the crystal structure of the CeZn1.35Ga2.65 and CeZnGa4 ternary phases

Two ternary compounds, CeZn1.35Ga2.65 and CeZnGa4, were prepared using the self-flux method. Their crystal structures were derived by direct methods from single crystal X-ray diffraction data. CeZn1.35Ga2.65 crystallizes in the BaAl4 structure type and CeZnGa4 in a structure related to the Ce2NiGa10-type, both with the space group I4/mmm. The refined structural parameters for CeZn1.35Ga2.65 and CeZnGa4 are a = 4.2717(2) إ, c = 10.6975(4) إ, V = 195.202(15) إ3 and a = 4.2944(5) إ, c = 26.147(3) إ, V = 482.21(10) إ3, respectively.
