Solid-state Synthesis Dimensional Reduction

In contrast to the synthetic accessibility of the above complexes using solution approaches, the synthesis of octahedral rhenium chalcogenide clusters requires the implementation of high temperature solid-state reactions, or the conversion of cluster-containing solids into soluble molecular species by the methods of cluster excision or dimensional reduction (see Section 7.2.2.1.8). While cluster excision has produced the mixed sulfide(selenide)-chloride clusters [Re6E4+ Clio 2 ] " ( = 1-3), the latter approach has led to the isolation of complexes with rhenium-chalcogenide cores [RegEgXg] - (E = S, Se X = C1, Br, I).
