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.
