Abstract

A large class of ternary Mo chalcogenides can be formed with the general formula MxMo6X8 where M is a metal, 0 ≤ x ≤ 4, and X = S, Se or Te (1). These compounds have a relatively complex crystal structure with rhombohedral symmetry and a rhombohedral angle that is close to 90° (2). The crystal structure of the ternary Mo chalcogenides (Chevrel phases) is shown in Fig. 1 for a compound with the formula REMo6S8 (RE = rare earth).
