Chalcogenide-bridged cuboidal clusters with M4Q4 (M = Mo, W; Q = S, Se, Te) cores

Abstract

Cuboidal cluster complexes having M₄Q₄ cores made up of transition and main group metals (M), and non-metallic e.g. chalcogenide elements (Q), constitute a rapidly expanding area of inorganic chemistry. Extensive preparation, structural and reactivity studies have been carried out on the Group 6 metals (M = Mo, W) and chalcogenide (Q = S, Se, Te) clusters, and are the main focus of this perspective. The aqueous solution chemistry provides an important reference point in considering redox and other relevant properties.
