The DyAg_~3In₃ compound was prepared by arc-melting of pure compact metals under an argon atmosphere. The crystal structure was refined from synchrotron powder diffraction data (space group Im-3, a = 15.1472(2) Å, Z = 24, R_p = 0.0792, R_wp = 0.1031, R_exp = 0.0231, refined composition DyAg_3.010In₃) and from conventional X-ray single crystal diffraction data (a = 15.1010(1) Å, R = 0.0423, R_w = 0.0433, refined composition DyAg_2.853In₃). The crystal structure belongs to the YbAg₂In₄ structure type, which is closely related to the structures of YbCd₆ and YCd₆.
