The interactions between the components in the ternary Zr-Ag-In system were studied. An isothermal section at 870 K was established by X-ray analysis. Two unknown ternary compounds have been found: ZrAg0.4In2.6-AuCu3 structure type (space group Pm (3) over bar m, a = 4.3644(4) Angstrom) and Zr5AgIn(3)-Hf5CuSn3 structure type (space group P6(3)/mcm, a = 8.735(3) Angstrom, c = 5.948(2) Angstrom). Their crystal structures were determined by powder X-ray analysis.
