Abstract
The intermetallic compound Cu9.1(1)TeSb3 prepared at 973 K is an
ordered member of the solid solution Cu64Te31Sb5-Cu70Te8Sb22 which
also exists, for more limited composition ranges, between 673 K
and 1173 K. It is a stuffed derivative of the structure type A15
(Cr3Si). Te is surrounded by twelve 3/4-occupied Cu-positions in
the vertices of a cubically-deformed icosahedron (Cu-Te = 2.614 Å)
which itself is nested in an Sb-icosahedron (Cu-Sb = 2.777 Å (x2)
and 2.603 Å). The Sb array corresponds to the Cr array in Cr3Si.
