A quasi‐planar dithiadiazafulvalene (DTDAF) with high electrondonating properties is reported. The chemical synthesis of a phenyl‐ N,N′ ‐bridged DTDAF (the Figure shows an ORTEP drawing of the DTDAF ⊕⊙ cation radical) is described together with the preparation of a charge‐transfer set by an situ trapping and investigations of teh structural and magnetic properties of this salt. Evidence for mixed valence states is presented.
