SnyNi4Sb12-xSnx (2.4 [less-than-or-equals, slant] x [less-than-or-equals, slant] 5.6; 0 [less-than-or-equals, slant] y [less-than-or-equals, slant] 0.31 at 250C) belongs to a new class of skutterudites in which the 8c site is fully occupied by Ni atoms. Sn atoms occupy two inequivalent sites (24g and 2a) and have a large thermal displacement parameter in 2a. Within the homogeneity range, electronic transport is primarily governed by the number of charge carriers, revealing a crossover from metallic- to a semiconducting behaviour with increase in x.
