A neutral complex of an azino–DTDAF compound with TCNQ

In the crystal structure of the title 1:1 complex, ethyl 2‐{5‐(ethoxy­carbonyl)‐2,3‐dihydro‐3,4‐di­methyl‐1,3‐thia­zol‐2‐yl­idene]­hydrazono}‐2,3‐di­hydro‐3,4‐di­methyl‐1,3‐thia­zole‐5‐carboxyl­ate–7,7,8,8‐tetra­cyano‐p‐quinodi­methane (1/1), C₁₆H₂₂N₄O₄S₂·C₁₂H₄N₄, the planar donor and tetra­cyano‐p‐quinodi­methane (TCNQ) mol­ecules are each located on inversion centres and are stacked alternately. The bond lengths indicate that, in this complex, the donor and acceptor are neutral, as confirmed by IR investigation.
