A neutral complex of an azino[bond]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), C(16)H(22)N(4)O(4)S(2) x C(12)H(4)N(4), 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.
