Reactivity of Chalcogenostannate Salts: Unusual Synthesis and Structure of a Compound Containing Ternary Cluster Anions [Co4(μ4-Se)(SnSe4)4]10

Abstract

A water and methanol mixture permits the transfer of the tin–chalcogen substructure of chalcogenostannate anions into the coordination sphere of transition-metal ions without decomposition. The reaction of K4[SnSe4] with [Co(en)3]Cl3 yields compound 1, which contains highly charged, purely inorganic ternary anions.
