Abstract
Quaternary phases, A(Mo2Re2)S8, A=Fe,Ni,Zn,Cu and Ga containing mixed tetrahedral (Mo2Re2) clusters have been synthesized and electrical properties examined in the range 77-300K. The compounds possess cubic symmetry and are n-type semiconductors except when A=Cu, which is metallic exhibiting p-type behavior. Isostructural GaMo4S8 is an n-type semiconductor. The type of bonding in these materials is discussed. © 1979.
