The use of Copper(Iota) halides as a preparative tool

The use of copper(I) halides as a preparative tool is discussed with respec t to the synthesis of adduct compounds with new polymeric and oligomeric ma in group molecules. By using this approach new polymers of main group eleme nts-some of which have been predicted by theoretical investigations-can be obtained in a crystalline state and are therefore accessible for a basic st ructural characterization. Thus, it becomes possible to compare the structu ral data, experimental data, and theoretical results. Mixed copper halide c halcogenides are accessible when complex copper thiometalates and copper ha lides are combined. These solid-state compounds are of special interest sin ce they provide experimental access to new main group molecules. In additio n, they exhibit a high copper ion conductivity when certain structural feat ures are present in the compounds. A survey is given of basic synthetic and general structural aspects.
