Ladder and web polymorphic forms of cocrystals of tetramethylpyrazinedioxide (TMPDO) and tetracyanoethylene (TCNE) are obtained by rapid or slow crystallization, respectively. In the thermodynamically less stable, purple (TMPDO) 2− TCNE crystals the donor and acceptor building blocks are linked through N + O − °C(alkene) interactions to form one‐dimensional ladders (see picture below).
