Crystalline sodium seleno- and telluro-carboxylates: Localization of negative charge on electropositive chalcogeno atoms

Article abstract of DOI:10.1016/S0040-4039(00)94449-6

Crystalline sodium seleno- and telluro-carboxylates were prepared from the corresponding bis(acyl)selenide and tellurides with sodium ethoxide. The salts have the unsymmetrical ionic structure where the negative charge is localized on the selenium or tellurium atom.
