Many chalcogen‐substituted derivatives of tetrathiafulvalene (TTF) are able to form metallic or even superconducting cation radical salts. The particular properties of bis(ethylenedithio)TTF (ET) prompted the synthesis of new oxygen‐containing analogues of ET. One such new molecule, ETOX, is presented, which, besides being a new π‐donor, is the first mono‐oxa derivative of ET. It is shown to be a promising donor for molecular metals and superconductors that gives cation radical salts with a variety of stoichiometries.
