The nature of bonding in some tellurium analogues of Chevrel and related phases is discussed in detail for the first time. The electronic effect, which is a characteristic feature of bonding in sulfides and selenides of this type, has been found not to occur in the closely related tellurides. A reason for this is suggested. Previously unrecognized features of bonding in Chevrel phase sulfides and selenides, and in Mo[sub 4]Ru[sub 2]Se[sub 8] and Mo[sub 1.5]Re[sub 4.5]Se[sub 8], are also reported. The bonding characteristics of compounds containing Mo[sub 6] units are shown to be different from the characteristics of those containing Mo[sub 6[minus]x]M[prime][sub x] (M[prime] = Ru, Rh, Re) clusters where the cluster metal M[prime] polarizes the chalcogen valence electrons. Cluster metal oxidation states have been found to influence both intra- and intercluster metal-chalcogen separations in a systematic and predictable fashion.
