Abstract

The crystal structures of Li_3.3Mo₆S₈ and Li_3.2Mo₆Se₈, Chevrel phases formed by the insertion of lithium into Mo₆S₈ and Mo₆Se₈, were determined by neutron diffraction powder profile analysis. The Mo₆S₈ and Mo₆Se₈ clusters are quite similar to those in other compounds of this type. The lithium atoms in both cases are disordered over the two concentric rings of available tetrahedrally coordinated small atom sites. For both compounds, occupancy of the outer ring is strongly preferred, and in Li_3.3Mo₆S₈ the inner lithium ring has a unique puckered geometry.
