A detailed study of
the Lu-Cu-Sn ternary system was
performed in the composition range Cu–LuCu5–LuCuSn–Sn at 670 K. The
crystal structure of two previously unknown stannides formed in this region was
determined using X-ray powder diffraction. The Lu1.8Cu9.2Sn2.8
compound crystallizes in the Dy1.9Cu9.2Sn2.8
structure type (space group P63/mmc),
whereas the Lu3Cu4Sn4 stannide belongs to the
Tm3Cu4Sn4 structure type (space group C2/m). The formation of a
substitutional solid solution LuCu5-xSnx up to 15 at.% Sn was
observed.

crystal structure of the Lu3Cu4Sn4 compound (SG C2/m).
