Crystal Structure of Hf2GaSb3
The structure of the new ternary compound Hf2GaSb3 was determined by means of X-ray powder diffraction. It crystallizes with the structure type Zr2CuSb3 which represents a ternary ordered derivative of the UAs2 type (Pearson symbol tP6, space group P-4m2, a = 3.89841(8), c = 8.62650(19) Å). The ternary compound can be regarded as an ordered, Ga-stabilized derivative of the high-temperature modification of the binary antimonide HfSb2 (structure type UAs2).
