Abstract

Chalcogenidotetrelates show a rich and complex chemistry encompassing intricate structures and useful materials. A step-wise coordination chemistry approach allows the sequential formation of multinary M/T/E anions (M = transition metal, T = tetrel, E = chalcogen) from simple T/E building blocks in solution. This way, a range of compounds displaying different structure types of molecular as well as extended multinary anions were obtained. To allow for even further variety, the approach can be extended to organo-functionalized chalcogenidotetrelates. Here, the organic shell of the inorganic cages plays a decisive role in reactivity and resulting structures. The formation structures and properties of these compounds will be discussed in detail in this perspective article.
