Chalcogen clusters

Standard Enthalpies of Formation of the Small Chalcogen Clusters E (n = 1-8)... 

Since 1990, several reviews have appeared covering silicon-chalcogen chemistry. These include the spectroscopic properties of silicon-sulphur compounds along with structural data1. The synthesis of metal-chalcogen clusters using (Me3Si)2X (X = S, Se,... 

Gallium-chalcogen clusters (Cp Gali)4 (E = S, Se) result from the reaction of (Me3Si)2E with Cp GaCl2, while the P—N heterocycle (8) can be thiolated at P(V) using (Me3Si)2S (equation 25)45.

The ability of PE spectroscopy to interrogate the whole range of valence orbitals of a molecular system has proved invaluable in investigating the electronic structure of metal-metal multiple bonds and small metal clusters. In the organometallic field, most attention has been focused on metal carbonyl dimers and small clusters, and their derivatives, on account of the high stability and volatility of these species. Metal chalcogen clusters of stoichiometry M4CP4E4 (E = O, S, Se) have also proved viable and fruitful candidates for PE spectroscopy. ...

The first structurally characterized lanthanide chalcogen clusters were isolated as decomposition products of monomeric or dimeric species. Trivalent tellurolate complexes Ln[TeSi(TMS)3]3 (Ln = Ce, La), which can only be isolated as dmpe derivatives, decompose in solution to yield...
