A new ternary intermetallic compound, DyGa_0.5-0.4Ge_1.3-1.4, was synthesized and its crystal structure was determined by X-ray powder diffraction (structure type Y(Ga_0.4Ge_0.6)_1.7, Pearson symbol oI16, space group Imma, a = 4.0641(3)-4.0709(3), b = 4.0870(3)-4.0845(3), c = 13.888(11)-13.8426(9) Å, Z = 4). The structure type Y(Ga_0.4Ge_0.6)_1.7 is closely related to the structure type GdSi_{1.4, and} belongs to the family of structures with trigonal-prismatic coordination of the smallest atoms.
