A class of metal cluster superconductors of particular Interest consists of ternary molybdenum chalcogenides, conmonly known as the Chevrel phases (13). These phases were the first type of superconducting ternary system found to have relatively high critical temperatures and exhibited the highest known critical magnetic fields (Hc2 before discovery of the copper oxide... 

The mechanism for cluster formation, and thus the molecular stmcture of the products, is strongly influenced by the special reaction conditions (temperature, type of copper salt used, type and size of the PR3 ligand). As expected very often the thermodynamically stable metal chalcogenides are formed, however, calculations have shown that the PR3-stabilized cluster complexes are metastable.
