Recently, the authors have been exploring the chemistry of metal polychalcogenides with various synthetic methods such as traditional room temperature solution and unusual molten salt techniques with considerable success. In order to expand the synthetic repertoire in this area, they have been experimenting with hydrothermal conditions to assess their potential as variable synthetic routes to novel metal polychalcogenides. Hydrothermal synthesis of chalcogenides is very little studied, despite its demonstrated usefulness in the synthesis of a variety of other important, and often inaccessible by other techniques, materials such as quartz and zeolites. Hydro(methano)thermal conditions have been used to prepare some very interesting metal monochalcogenide compounds by using alkali carbonates as mineralizers. Using Se{sub x}{sup 2{minus}} as mineralizers, the authors have uncovered a new route to novel polychalcogenides. They report here the first hydrothermal synthesis of a metal polychalcogenide complex, the remarkable (Mo{sub 12}Se{sub 56}){sup 12{minus}} (I), possessing an extraordinary structure.
