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, Rp = 0.0792, Rwp = 0.1031, Rexp = 0.0231, refined composition DyAg3.010In3) and from conventional X-ray single crystal diffraction data (a = 15.1010(1) Å, R = 0.0423, Rw = 0.0433, refined composition DyAg2.853In3). The crystal structure belongs to the YbAg2In4 structure type, which is closely related to the structures of YbCd6 and YCd6.
