The title complex, C17H9N5•C6H4S4, contains -deficient bis(dinitrile) and TTF molecules stacked alternately in columns along the a-axis direction; the interplanar angle between the TTF molecule and the isoindolinyl C4N[C(CN)2]2 moiety is 1.21 (4)°. The N-allyl moiety in the TCPI molecule is oriented at an angle of 87.10 (10)° with respect to the five-membered C4N ring, and the four C N bond lengths range from 1.134 (3) to 1.142 (3) Å, with C-C N angles in the range 174.3 (3)-176.9 (2)°. In the TTF system, the S-C bond lengths are 1.726 (3)-1.740 (3) and 1.751 (2)-1.763 (2) Å for the external S-C(H) and internal S-C(S) bonds, respectively.
